Multiplexer D2030M Units, can be installed in the field, close to input sensors, for data acquisition from Hazardous Area and connected to a Safe Area PLC/DCS or other devices, via 2 wire communication link and Gateway D2050M Unit, saving wiring, cables and costs.
The Units are primarily intended for Hazardous Area acquisition from contacts or proximity detectors. D2030M scans all channels and stores all data in a memory buffer, where they can be rapidly accessed by the Modbus Gateway D2050M Unit. Each Mux D2030M Unit accepts directly up to 32 input channels and is expandable to 128 channels by using four D2030M Units with a single Modbus Gateway D2050M Unit.
