IO61A02 — Multifunction Controller with Limit Inputs
The IO61A02 is designed for more flexible forward/reverse automation. It provides four control inputs for forward, reverse and two limit signals.
Key features
-
DC 12V or 24V operating version.
-
Nine selectable operating modes.
-
Forward and reverse trigger inputs.
-
Two limit-signal inputs.
-
Active-low NPN-compatible trigger logic.
-

-
Compact board measuring approximately 89 × 62 × 22 mm.
Typical applications
-
Automatic curtains and doors.
-
Electric pushers and linear actuators.
-
Mechanisms requiring independent forward and reverse commands.
-
Systems using microswitches, proximity sensors or compatible external controllers.
Why choose it?
The IO61A02 is a good candidate when the application needs configurable operating logic and limit-switch integration. It offers more flexibility than a simple latching relay.
Important: The 30A relay rating should not be interpreted as a guaranteed continuous 30A motor-load capacity. Motor starting and stall currents must be considered. <Cite refs={["turn875698search2"]} />
IO52B02 — Programmable Timer and Cycle Controller
The IO52B02 is intended for applications where the motor must operate in a defined sequence, rather than simply changing direction whenever a switch is pressed.
Key features
-
DC 12V controller supply.
-
Forward, reverse and stop inputs.
-
Low-pulse and low-level trigger modes.
-
Adjustable timing from 0.1 seconds up to 9,999 seconds or minutes, depending on the selected time range.
-
Configurable cycle counts, including continuous cycling.
-
Six operating modes.
-
Relay contacts rated up to 30A under specified conditions.
Typical applications
-
Automatic reciprocating mechanisms.

Applications requiring programmed running, stopping and reversing intervals.
Why choose it?
Choose the IO52B02 when the motor must follow a timer-based sequence or repeat a programmed cycle.
The controller supply and motor power connections are separate. The motor needs its own correctly rated power source, and the applicable motor voltage and load limits must be confirmed for the chosen wiring configuration. <Cite refs={["turn875698search1"]} />
IO53A02 — Flexible Controller for Custom Projects
The IO53A02 provides programmable forward/reverse control with multiple timing and triggering options.
Key features

Adjustable timing and cycle operation.
-
Six operating modes.
-
Published relay load-current recommendation: less than 5A.
Typical applications
-
Toy and model mechanisms.
-
Garage-door prototypes.
-
Custom motor-control projects.
-
Small automation systems requiring programmable movement.
Why choose it?
The IO53A02 is worth considering when a project needs flexible control logic but does not require the higher relay rating of the IO52B02.
Its published motor-wiring examples include both DC and AC motor arrangements. Because the motor power circuit can involve hazardous voltage, follow the specific wiring diagram and use appropriate electrical isolation and protection. <Cite refs={["turn518718search0"]} />
IO55C02 — Wireless Remote Control with Speed Adjustment
The IO55C02 is designed for applications where users want to control motor direction and speed remotely.

Typical applications
-
Remote-controlled curtains and actuators.
-
Adjustable mechanical equipment.
-
Brushed DC motor projects.
-
Devices requiring wireless speed and direction control.
Why choose it?
Choose the IO55C02 when the user needs a handheld remote and variable-speed control rather than only wired trigger inputs.
Use a compatible remote, and verify the motor's rated power, operating current and stall current before installation. <Cite refs={["turn875698search3"]} />
IO57E02 / IO58F02 — Forward/Reverse Control with Overload Protection
These models combine motor direction control with adjustable overcurrent protection, making them relevant where motor overload or mechanical jamming is a concern.
Key features
-
DC 12V and 24V versions.
-
Designed for brushed DC motors.
-
Forward and reverse control.
-
Selectable momentary or self-locking operation.
-
Adjustable overcurrent protection.
-
Published current options include 10A, 20A and 30A versions, depending on the selected model.
-
The published specifications distinguish short-term current from long-term operating current.
Typical applications
-
Brushed DC motor systems.
-
Actuators that may encounter mechanical resistance.
-
Small machines requiring adjustable current limits.
-
Projects where basic overload protection is desirable.
Why choose it?
Choose this family when protection is a key requirement, rather than selecting a controller based only on its maximum current rating.
The short-term current rating is not the same as continuous operating current. Confirm the exact version, current setting and thermal conditions before use. <Cite refs={["turn875698search6"]} />
DR26F01 — Compact Latching Polarity-Reversal Relay
The DR26F01 uses a bistable DPDT relay to switch output connections and reverse polarity when wired appropriately for a brushed DC motor.
Key features
-
Wide operating supply range: DC 7–40V.
-
Maximum listed load current: 5A.
-
Inductive-load limit: 2A.
-
Low-pulse trigger input.
-
Bistable operation: one trigger changes the relay state; another trigger changes it back.
-
Approximate board size: 39.5 × 33.3 × 23.3 mm.
-
Low standby current.
Typical applications
-
Small brushed DC motors.
-
Simple polarity-reversal circuits.
-
Low-power switching.
-
Toy and DIY electronics projects.
Why choose it?
The DR26F01 is ideal when simple, low-power latching operation is sufficient. It is not a substitute for a programmable controller with multiple limit inputs, timer sequences or dedicated motor-protection functions.
The relay state is retained until another trigger or a power interruption changes the operating condition, depending on the wiring and circuit behavior. <Cite refs={["turn518718search2"]} />
DR56C01 — Simple and Economical Polarity Reversal
The DR56C01 is a smaller, simpler alternative for low-current polarity-reversal applications.
Key features
-
DC 6–24V input.
-
Maximum listed load current of 2A.
-
Inductive-load limit of 1A.
-
Low-pulse trigger.
-
Self-locking/bistable relay operation.
-
Compact board, approximately 30 × 30 × 16 mm.
Typical applications
-
Small DC motors.
-
Toy mechanisms.
-
Low-current polarity switching.
-
Compact electronic projects.
Why choose it?
Choose the DR56C01 when the motor current is low and only simple toggle-based direction reversal is required.
For larger motors or loads with high starting current, select a controller with suitable electrical capacity and protection. <Cite refs={["turn875698search4"]} />
N467D01 — RS485/Modbus Programmable Motor Controller
The N467D01 is intended for systems that require motor control through industrial communication rather than only physical switches or a handheld remote.
Key features
-
Supports Modbus RTU over RS485.
-
Forward, reverse and stop commands.
-
Adjustable delay and cycle settings.
-
Parameter configuration through registers.
-
Undervoltage lockout, short-circuit protection and overtemperature shutdown are listed features.
-
Versions are available with different current capabilities and operating-voltage ranges.
Typical applications
-
PLC-controlled linear actuators.
-
Industrial automation prototypes.
-
Distributed motor-control systems.
-
Equipment that requires remote commands and programmable operation.
Why choose it?
Choose the N467D01 when the motor must be integrated into an RS485/Modbus control network. It offers a different control approach from relay-based modules intended for standalone operation.
Check the selected current version carefully: the published voltage ranges differ between versions, so the 1A and 2A variants should not be assumed to have identical specifications. <Cite refs={["turn875698search5"]} />

5. How to Select the Right Motor Controller
Before choosing a module, consider these five questions:
-
What type of motor are you using? Most of these models target brushed DC motors or specific relay-switched loads. Do not assume they support brushless DC motors or stepper motors.
-
What are the motor's voltage and current requirements? Check rated current, startup current and stall current—not just the controller's headline maximum.
-
Does the application need limit switches? Curtains, doors and linear actuators often need reliable end-of-travel detection.
-
Is timing or wireless operation required? IO52B02 is suitable for timed sequences, while IO55C02 adds wireless control and speed adjustment.
-
Is protection or industrial communication important? Consider IO57E02/IO58F02 for adjustable overcurrent protection or N467D01 for RS485/Modbus integration.
