R4CVA02 FAQ

Can I connect the R4CVA02 directly to a PLC? Or do I need an additional board?

I want to use this for 4-40mA CO sensors. There are 216 existing sensors, but the board doesn't support Modbus, so I want to replace the board with this.

I need to fix it in the existing plastic housing.

Eletechsup: Any PLC with an RS485 interface can use it directly. It uses the Modbus RTU protocol; check the manual first.

Is it possible to provide a 24V supply, but the sensor output will be 5V?

Eletechsup: Yes, it's possible. However, I suggest purchasing a sample for testing first.
