G.M. International Intrinsically Safe Analog-Temperature Multiplexer DIN-Rail Model D2010M. 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. D2010M scans all channels using state of the art solid state isolated relays, and stores all data in a memory buffer, where they can be rapidly accessed by the Modbus Gateway D2050M unit. Each D2010M unit accepts directly up to 16 input channels and, by adding from one to three D2011M units, is expandable to 64 channels in blocks of 16 channels each. Multiplexer D2010M units can be installed in the field, close to input sensors, for data acquisition of signal from Hazardous Area/Hazardous Locations Zone 0-1-2 or Class I, Class II, Class III, Division 1-2. The units are primarily intended for Hazardous Area/Hazardous Locations acquisition of low level signals from mV, thermocouples, thermoresistances or mA (via external shunt device like D1090Q four channel shunt resistor) sources.
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.
