INTRINSICALLY SAFE ANALOG - TEMPERATURE MULTIPLEXER SLAVE UNIT (16 INPUTS)
Multiplexer Units D2010 can be installed in the field, close to input sensors, for data acquisition from Hazardous Area and connected to a Safe Area PLC/DCS or other devices, via 2 wire communication link and Interface Unit D2050M, saving wiring, cables and costs.
The Units are primarily intended for Hazardous Area acquisition of low level
signals from Thermocouples, RTDs, mV or mA sources.
D2010 scans all enabled 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 Unit D2050M.
Each Mux Unit accepts directly up to 16 inputs channels and, by adding 1 to 3 Expander Units D2011M, is expandable to 64 channels in blocks of 16 each.
Four D2010M Units, connected with twelve D2011M Expanders reach 256
inputs with a single Modbus Gateway Unit D2050M.
Redundant cummunication is obtained by dual data/supply interface line.
Safety Parameters mantain compatibility with Gas Group II C even in redundant mode.
A/D Converter, Integrating type, High Rejection, High Accuracy (18 bits), automatically calibrates Zero and Span providing accurate and stable measurements. All parameters are software configurable by serial commands via D2050M Gateway Unit.
