Novus DigiRail-4C RS485 Four counters/digital inputs

Description


The DigiRail-4C has 4 inputs designed to accept four Volt Free Digital inputs. Its compact DIN Rail mountable form allows it to be mounted almost anywhere and the DigiRail-4C connects to Serial ModBus-RTU networks on standard 2 wire RS485. The DigiRail-4C is fully configurable and can be used with any PLC, Data acquisition software or SCADA systems that support the ubiquitous ModBus-RTU protocol.

The DigiRail-4C inputs are electrically isolated from the serial interface and the module supply thus avoiding interference.
The DigiRail-4C is easily configured and calibrated using the free DigiConfig software for Windows (if you need a RS485 converter the Novus USB i485 will be an appropriate addition).
The DigiConfig software also features device detection technology, automatically detecting all DigiRail devices on the modBus network allowing quick and easy configuration.
