The controllers are powered at 220 Vac and automatically recognise the connected sensor via the serial interface and Modbus 485 protocol.
They have the necessary functions for configuration and local storage of acquired data; the single-parameter controller has a 4-20 mA analogue output, while the multi-parameter controller can be optionally integrated with external analogue-digital interface modules.
Both controllers also have a serial output with Modbus 485 protocol to external plant units (PLC, data-logger).
