ATR121

Controller Double setpoint

Controller 32x74mm, Single control loop, 3-digits Display. Distinctive feature is the high configurability, resulting in a limited number of ordering codes.

Universal analogue input, selectable for a wide range of sensors, both for industrial or civil applications. Relay/SSR outputs, programmable as command/alarm/event. Optional RS485-ModbusRTU/Slave.

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