D2052M

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 D2052M 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 D2052M unit is equipped with 32 relay output SPDT contacts. 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. The relay output is of the changeover type allowing the use of normally close or normally open contacts.
