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