AMR-CU70B, AMR-CU71B – Control unit with a display
AMR-CU70B (or AMR-CU71B) is a freely programmable controller which comes in the very same design as AMiT’s AMR-OP70 on-wall controllers series. However, unlike them, it features 2 extra RTD inputs (resistive temperature sensors, contact), 2 digital outputs and 1 analogue output with the range 0 to 10 V. Thanks to the option to program your own control algorithm and display layout, the controller is more than suitable for simple control tasks with autonomous temperature measurement and local control.
The controller features the RS485 communication line supporting MODBUS RTU, DB-Net or ARION protocol and can be therefore easily connected to a host device system or a computer for further processing of measured data. Memories RAM and RTC are backed with a replaceable battery. The controller is designed for superficial mounting, either horizontal or vertical.
