free@home Heating Actuator, 12-fold, 230 V, MDRC
ABB HA-M-0.12.1

free@home Heating Actuator, 12-fold, 230 V, MDRC

Product code: 2CDG510009R0011
For controlling thermoelectric actuating drives in heating/cooling systems. The outputs are protected against short-circuit and overload. The bus can be connected via enclosed terminal block.
Price (Excluding GST)


This devices has twelve channels and serves as an actuator for the activation of heating systems via conventional thermal actuating drives.

  • Twelve channels for the activation of actuating drives.
  • Per channel, each device supports voltages of 24 V AC up to 230 V AC (this makes the use of all conventional thermal actuating drives possible).
  • Three channels can be protected together by a circuit-breaker.
