ES/S8.1.2.1
Electronic Switch Actuator, 8-fold, 1 A, MDRC
Product code:
2CDG110059R0011
For controlling thermoelectric and motor-driven valve drives in heating/cooling systems and for noiseless switching of loads at 24...230 V AC/DC. The 8 semicondcutor outputs are protected against short circuits and overload.With manual operation.
Description
The Electronic Switch Actuator ES/S 8.1.2.1 is a modular installation device in Pro M design. The device features four semiconductor outputs for control of electrothermal valve drive in heating and cooling systems.
The outputs can be operated with either DC or AC voltage (24-230 V AC/DC).
The outputs can be combined as required, so that, e.g. output A controls electro-thermal valve drives, output B switches the lighting and outputs C and D control electro-motor actuator drives.
Each output is short-circuit and overload protected. The outputs can be directly controlled using the manual pushbuttons. The LEDs on the front of the device signal the status of the outputs.
