ATR171

Controller multi-setpoint / Dual input

Controller 72x72mm, Single/Dual control loop. A limited number of ordering codes still guaranteeing high flexibility of application through high configurability at software level.

One or two analogue inputs, selectable for a wide range of sensors, with the possibility to relate them to mathematical functions. Outputs programmable as command/alarm/event or analogue retransmission . Extended power supply range 24....230 Volt ac/dc with galvanic isolation (also between inputs/outputs).

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