The local controllers are powered at 110/220 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).
The handheld controller is battery powered and it can manage one sensor or probe for field use.
