Central pulse switch ISK 42 with additional relay contact and ZI
ISK 42
In electrical installations with several sub-distribution boards and residual current circuit breakers, the ISK 42 switchgear developed for this purpose can be used to create an economical central ON-OFF control system. The central control inputs are galvanically isolated from the inputs and outputs on the supply side by optocouplers.
The ISK 42 has a second potential-free relay contact (10A, normally open) and a central pulse input. In contrast to conventional pulse switches with central control, ISK 42 can thus be connected between different networks, RCDs or potentials without decoupling relays.
- The central control inputs are isolated from the inputs and outputs on the power side and can be controlled with AC or DC voltages of 8-230 V.
- Central inputs (galv. isolated) for ZE (central ON), ZA (central OFF), ZI (central pulse ON/OFF).
- Additional relay output.
Applications
Central lighting activation by means of burglar alarm systems with presence detectors, central lighting on/off switching of building sections by means of central panel, time switch or twilight switch.
