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 D2053M unit is primarily intended for replication of proximity sensor or voltage free
contact status of devices located in Hazardous Area/Hazardous Locations in the
Safe Area/Non Hazardous Locations. When connected to D2050M unit, it repeats the
status of each D2030M digital input multiplexer unit.
The unit is driven by the Gateway D2050M via a dedicated bus.
Application of this devices allows the reduction in cabling complexity where digital status
are to be repeated in discrete form, in addition to the capability of analyzing them via
Modbus. The D2053M unit is equipped with 32 optocoupled transistor output.
The repeaters have the same channel capability as the digital field devices, so that
every input unit can be repeated on an output unit.
The assignment between input (field) and output (Safe Area/Non Hazardous Locations)
devices is managed by the software of the D2050M and corresponding internal settings.

Features:
• Output Repeater for D2030M Digital Multiplexer.
• Opto isolated voltage free Transistor Output Signals.
• High density, 32 channels per unit, 128 channels per system.
• EMC Compatibility to EN61000-6-2, EN61000-6-4.
• Simplified installation using standard DIN Rail mounting units.
