DRR245

Multisetpoint Controller

Signals converter

DIN rail-mounted Controller, single control loop. Distinctive feature is the high configurability available in a single ordering code.

Beside operation as multi-setpoint PID controller, the unit can be ideally used as signals converter thanks to universal analogue input (selectable by parameter for up to 18 different signals) and the analogue output which is galvanically isolated and programmable for rescalable retransmission of process/setpoint value.

RS485-ModbusRTU, Loop Break Alarm by current transformer.

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