I.S. Multiplexor – D2000

D2000M

The D2000M Multiplexor System allows the acquiring of multiple Analogue and/or Digital signals from sensors in Hazardous Area to a Gateway in Safe Area.

The Gateway D2050M communicates with PC/PLC/DCS via RS232 or Modbus redundant lines with a documented protocol, allowing maximum interoperability.

Key Features

• ATEX certification BVS 06 ATEX 101 X (download):
  Gateway: II (1)G [EEx ia] IIC
  Field units: II (1)2G EEx ia IIC T4
• High density, up to 256 Analog Inputs (TC,RTD,mV from D2010M) and up to 128 Digital Inputs (contact / proximity from D2030M) in the same system (expandable up to 7936 inputs by cascading multiple Gateways via Modbus)
• Inputs from Zone 0, 1, 2
• Input sensors: 2-3-4 wire RTD, Pt100, Pt50, Ni100, Cu100, Cu53, Cu50, Cu46, Thermocouples A1, A2, A3, B, E, J, K, L, Lr, N, R, S, T, U.
• Robust Isolation (+- 200V channel to channel), provides high immunity against interference and ground loops
• Intrinsically Safe for installation in Zone 1, 2
• Field Units can be placed up to 5 km from Gateway
