DigiRail 2A Dual Universal Analog Input Modbus Module

DigiRail 2A Dual Universal Analog Input Modbus Module

The Novus DigiRail series of Modbus RTU IO modules are rugged, isolated DIN rail mount units for SCADA or PLC systems. The DigiRail-2A features 2 universal analog inputs that accept a wide variety of temperature sensors and analog signals.

 

Input (each input programable):   Output:
J, K, T, E, N, R, S, B Thermocouples   Modbus RTU
Pt100   RS-485
0 to 50 mV   1,200 to 115,200 bps
0 to 20 mV   E/O/N parity
-10 to 20 mV    
0 to 5 V ¹    
0 to 10 V ¹   Power:
0 to 20 mA   10 to 35 VDC
4 to 20 mA   ≤50 mA

Note 1: The use of voltage scale inputs require moving jumpers inside the unit

The DigiRail units are configured over Modbus using a simple Windows utility (included on CD in the box and available from the Novus website). You will need a serial or USB to RS-485 converter to communicate with the unit from a PC.

Features:

  • 2 Analog inputs programmable for thermocouples (J, K, T, E, N, R, S, B), Pt100, mV, V, mA
  • Cold junction compensation for thermocouples and compensation for Pt100 3-wire cables
  • Open loop detection for thermocouples, Pt100 and mV
  • Sampling rate for 1 analogue input: 10Hz for mV, V and mA. 5Hz for thermocouples and Pt100
  • Electrical isolation between inputs and supply/serial ports: 1000Vac
  • 17 bit analog input resolution
  • User defined linearisation for the analog inputs
  • 10 to 35 VDC powered, 50 mA maximum current
  • 2-wire RS485 communication with Modbus RTU protocol. Configurable address and baud rate (1,200 to 115,200 bps)
  • LED indicators for communication and status
  • Accuracy (at 25°C): Pt100, mV, V and mA: ±0.15% of full scale. Thermocouples: ±0.25% of full scale.
  • Temperature effect: 0.003% of full scale/°C.
  • Cold junction compensation for thermocouples: 1°C at 25°C. ±0.05°C/°C
  • 1000 VAC isolation from inputs (analogue or digital) and power or communication.
  • Windows based configurator software.
  • Dimensions: 72 × 78 × 19 mm.
  • Mounts on standard 35 mm DIN rail.
  • Working temperature: 0 to 70 °C.
