Asea Brown Boveri C150 0000 STD Process Controller

ABB Commander C150/0000/STD is a 1/8‑DIN universal temperature and process indicator/controller that accepts a universal input and provides a built‑in transmitter power supply, plus outputs for analog, relay and logic signals. A built‑in 5 A alarm relay is standard, with LEDs indicating active alarms; an optional RS485 serial board enables Modbus communications with PLCs/SCADA. The unit offers 4–20 mA retransmission of the process variable and, when configured, flow totalization (6 digits) for simple differential‑pressure flow loops or batch totalization. The design supports up to two additional alarm relays via the Multiple Alarm Option for expanded alarm signaling. The C150/0000/STD designation identifies the standard ABB Commander C150 configuration in the family for temperature and process control applications.
