MB2DI2RO (2DI+2RO)
2Digital Input + 2Digital Output (Power Relay)
RS485 ModBus Remote Terminal Unit
RTU module which comes
with 2 digital inputs and 2 power relay outputs.
The inputs can collect from
dry or wet contact signal with the flexibility to set the input circuit as common
anode or common cathode.
