The CS-MDAS-DCU-IO is a telecontrol intended for remote monitoring and control of Medium Voltage switch gear equipments, disconnectors, load break switches and ring main unit in energy distribution networks. The CS-MDAS-DCU- IO consists of one RS232/RS485 port and one 10/100 Ethernet port.The supported protocols are IEC 60870-5-104 for remote connectivity and Modbus-RTU or DLMS/COSEM for energy meter connectivity. The Ethernet port is also used for configuration and diagnostics. The CS-MDAS-DCU-IO is designed for DIN rail mounting and have 19 digital inputs and 12 digital outputs. The unit also provides secure control and reliable control operations via SCBO(Select Check-Before Operate.)
