Redundant field lines for communication/supply
Modbus interface RTU protocol on redundant RS-485
RS-232 port for system configuration
Three port isolation, Input/Output/Supply
EMC Compatibility to EN61000-6-2, EN61000-6-4
High reliability, SMD components
Configurable by SWC2090 software (free of charge) or user software
Modbus output allows savings on PLC/DCS I/O cards cost
Lower cables, installation and maintenance costs
Simplified installation using standard DIN Rail mounting units
Repeat Hazardous Area/Hazardous Locations input contact or proximity detector in Safe Area/Non Hazardous Locations via D2052M unit (relay output) or via D2053M unit (transistor output).
The Power Supply Gateway D2050M Unit, mounted in Safe Area, provides Intrinsically Safe protection to the 2 wire communication link, and supplies power to D2010M, Expander D2011M, and Digital Multiplexer D2030M Units, installed in Hazardous Area, close to input sensors. Field units acquire data and pass it on to the Gateway, which makes it available via ModBus or RS-232 ports to a Safe Area PLC/DCS or other devices saving wiring cables and costs. The Unit is primarily intended to interface field Mux with the PLC/DCS systems via Modbus serial lines with redundant communication.
