The analogue inputs read thermocouples, Pt100\/Pt1000, NTC and mV, V or mA signals directly at 16-bit resolution, the analogue outputs provide 0-20mA, 4-20mA or 0-10V, and the relays give volt-free contacts for alarms, contactor coils and valves up to 250Vac.\u003c\/p\u003e\n\u003cp\u003eEvery DigiRail Connect model has Ethernet, RS485 and Micro USB on board. It works as a Modbus RTU slave on an existing RS485 network or as a Modbus TCP server on Ethernet, and can act as a transparent Modbus TCP to RTU gateway, so an Ethernet PLC or SCADA system can read RS485 instruments wired to its terminals with no register mapping.
