ABB Heating Actuator HA-M-0.12.12 12-fold 230 V REG BJE

The ABB Heating Actuator HA-M-0.12.12 is a KNX bus-compatible, 12-channel heating actuator designed for controlling electrothermal valve drives in building automation systems. It features 12 independent outputs, each rated at 230 V AC and 0.12 A, with a total output current of 1.44 A. The actuator supports both 2-point (ON/OFF) and PWM control modes, making it versatile for various heating applications. It is mounted on a DIN rail (MDRC) with a width of 12 modules (216 mm) and offers manual operation and LED status indication per channel. The device includes short-circuit and overload protection per channel, ensuring reliable operation. Power for the logic is supplied via the KNX bus, while the outputs require mains power. The actuator is suitable for use in residential and commercial building management systems.
