When such a requirement exists, the NCS Net Concentrator System remote I/O product simplifies the task of gathering signals scattered through multiple processing units or locations.  The NCS is Class I Div 2/Zone 2 approved and accepts a wide range of inputs including RTD, TC, Ohms, Potentiometer, mV,  mA and Volts.  Each NCS remote I/O station can accept up to 128 I/O points.  It supports RS-485 MODBUS RTU so up to 32 NCS systems without repeaters can be multi-dropped on one twisted pair and brought back to a MODBUS host monitoring system.  The easy to configure NCS has 500V of channel-to-channel isolation and has an ambient operating temperature specification of -40 to 85C (-40 to 185F).


Key Attributes:

  • The wide range of I/O types and number of points
  • Class I Div 2/Zone 2 approval
  • MODBUS RTU support
