Module multiplexer D2010M

digitalanalogmulti-channel

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. 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. 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. Four D2010M units, connected to twelve D2011M Expander units, achieve 256 inputs with a single Modbus Gateway D2050M 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.
