ATR243

Controller multi-setpoint

Controller 48x48 mm (1/16 Din), single control loop. Distinctive feature is the high configurability, resulting in a limited number of ordering codes.

Universal analogue input selectable for over 15 different types of sensor, beside SSR-Relay-V/mA outputs programmable as command/alarm/event, or analogue retransmission. Optional RS485-ModbusRTU and Loop Break Alarm by current transformer. useful extended power supply range 24....230 Volt ac/dc galvanically isolated.

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