Eco COM BCM ULP is a communication module that is installed behind the Micrologic control unit of ComPact NS630b-1600 devices. It receives and transmits information between the communication network and the Micrologic control unit. It uses the Modbus communication protocol for full compatibility with monitoring management systems. The ECO COM BCM ULP module is limited to the transmission of meter data and status. It must be connected to a communication interface (IFM for Modbus or IFE for Ethernet) to enable full communication capabilities. An infrared connection transmits data between the Micrologic and the communication interface. The current is 30 mA at 24 V DC. It comes with a set of microswitches, a kit for connection to voltage triggers, and a terminal block.
