MCU30 – MODBUS NODE with 3 digital inputs


The MCU30 is designed to monitor digital contacts, such as open fire doors, and transmit them via ModBus-RTU. Up to 31 MCU30 can be queried within an interface bus.
The individual nodes can be addressed via DIP switches or via the configuration software. Due to the round shape of the PCB, the MCU30 are ideally suited for installation in 68mm flushmounted boxes.
