Description:

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.
