DESCRIPTION The Compactcontroller is designed as a gas detection system for connection of max. 10 SB2Units (SB2 + SensorCartridge) via its own field bus. The controller monitors the measured values and activates the alarm relays if the specified max. 4 alarm thresholds for pre- and main alarm are exceeded. The analog 4–20 mA output provides either a sum signal of all or certain measured values or the signal of one measured value. The SIL2-compliant self-monitoring in the Compactcontroller as well as in the connected SB2Units activates the fault signal in the event of an internal fault as...
