ATR401

Controller multisetpoint /Dual input

Controller 48x96mm (1/8 Din), Single/Double control Loop. Distinctive feature is the high configurability, resulting in a limited number of ordering codes.

Two analogue inputs are selectable for a wide range of sensors and can be related to mathematical operations like mean/difference/addition. Remote setpoint by analogue input is also available. Variable number of outputs, programmable as comman/alarm/event or analogue retransmission. RS485-ModbusRTU. Useful extended supply range 24....115/230 Volt ac/dc galvanically isolated, also between inputs/outputs.

User-friendly operation, programming tools for quick set-up (MEMORY-CARD, programming and monitoring software LABSOFTVIEW).
