G.M. International 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.
G.M. International(GMI) offers a comprehensive range of intrinsic safety (IS) barriers designed to protect field devices located in hazardous areas. These barriers ensure safe signal transmission between the field and the control system by limiting voltage, current, and power levels. GMI products focus on cost-effective protection, robust performance, and compatibility with standard industrial instrumentation.

Advantages of GMI Safety Barriers
* High cost-performance ratio: Ideal for users seeking reliable explosion protection at an economical price.
* Stable and robust design: Ensures consistent signal integrity even in harsh industrial environments.
* Simple installation and wiring: Suitable for general-purpose applications and fast project deployment.
* Compatible with most field transmitters and sensors: Supports standard analog signals such as 4–20 mA and contact signals.
