Product Name: 8 Channel 24V Relay Shield Module RS485 PLC IO Expanding Board For Arduino NANO V3.0

Package inlcuded(Ship according to the item you purchased):

24V 8 channel PLC relay board for NANO V3.0

Product Features:

1 Operating voltage: DC 24V

2 Operating Current : Standby current (Digital tube OFF) 12MA, Standby current 48MA (Digital tube ON), 1 relay open 76MA, 2 relays open 104MA, 3 relays open 131MA, 4 relays open 162MA,5 relays open 184MA, 6 relays open 209MA, 7 relays open 255MA, 8 relays open 288MA

3 On-board resources: 1x RS485 Interface 8x opto-isolated inputs (low level trigger, NPN type), 4x buttons, 1x 4 bit digital tube display, 1x NANO V3.0 slots, 8x relay outputs

4 Size 150*72*19mm(Only Board)

5 Weight : 118g(Only Board), 228g(with shell)

We provide the code(sketch) can only achieve a simple delay function,The delay time is adjusted by modifying the delay parameter of the code(sketch).

If you need more functionality, write your own code. We do not provide additional code(sketch) and technical support

How to use: See video ''DN22D04 DEMO''(You can search for videos on GOOGLE)

Note: DN22D08 can not work independently, must be under the control of the NANO V3.0 board to work,If you do not have a NANO V3.0 board, Please purchase the kit ''NANO V3.0''

Application examples:

As long as you write ARDUIUO code(sketch),You can use it to achieve a variety of delay timer function,such as:

RS485 Master-Slave Device(PLC MCU)

Motor forward and reverse,

Timing on,

Timing off,

Power-up delay,

Trigger delay,

Infinite loop delay,

A finite number of cyclic delays,

Power sequencer,

And so on.

Application 1: Through the programming of NANO V3.0, various delay customization functions can be realized instead of PLC.

Application 2: It can be used as an RS485 master device instead of PLC/PC/touch screen to control various RS485 slave devices.
