Gateway - Power Supply Unit
for Multiplexer D2000M Series
DIN-Rail Model D2050M
General description:
D2000M series Intrinsically Safe Multiplexing System consists of one to four
Analog-Temperature Multiplexer units model D2010M, up to twelve Expander units
model D2011M, or up to four Digital Multiplexer units model D2030M, mounted in
Hazardous Area/Hazardous Locations Zone 1-2, Gas Group IIC-IIB-IIA T4 or
Class I, Division 1-2, Group A, B, C, D T4 and connected via a single/redundant 2 wires
data communication/supply line to a Modbus Gateway unit model D2050M,
mounted in Safe Area/Non Hazardous Locations and connected to a PLC, DCS or PC.
The Gateway D2050M unit, mounted in Safe Area/Non Hazardous Locations, provides
intrinsically safe protection to the 2 wires communication link, and supplies power to
Analog-Temperature Multiplexer D2010M and Digital Multiplexer D2030M units,
installed in Hazardous Area/Hazardous Locations, close to input sensors, for data
acquisition and connects the field multiplexers to a Safe Area/Non Hazardous Locations
PLC, DCS or other devices, saving wiring cables and costs.
The unit is primarily intended to interface field multiplexer with the PLC, DCS systems
via Modbus serial lines with redundant communication.
Units D2010M, D2011M and D2030M scan all channels and store all data in a memory
buffer, where they can be rapidly accessed by the Modbus Gateway unit D2050M.
Each multiplexer unit D2010M accepts directly up to 16 input channels and, by adding
from one to three D2011M, is expandable to 64 channels. Four D2010M units,
connected to twelve D2011M expanders, achieve 256 inputs via one Modbus Gateway
D2050M. D2030M unit accepts up to 32 digital input channels and up to four D2030M
units (128 channels) can be connected to the D2050M Gateway.
One D2050M unit can support up to 256 analog input channels from D2010M, D2011M
or 128 digital channels from D2030M unit.
Redundant communication is obtained by dual data/supply interface line.
Safety parameters mantain compatibility with Gas Group IIC or Gas Group A and B,
even in redundant mode.
All parameters are software configurable by serial commands. Functions and serial
commands for RS-232 and RS-485 protocols are provided in the instruction manual.
