Board containing 4 relays. When connected to the LAN controller: LK3.5+ (including LK3.9), LK4, LK3.0, LK2.5, it allows you to turn on, turn off and reset each relay independently. Their status is indicated by LEDs. The main application is to control 4 electrical devices.
The high-quality relays used by the Polish company Relpol are characterized by high resistance to surges. The special design of the contacts, which removes metal oxides with each switching, additionally extends the time of failure-free operation.
The set includes a 30 cm control cable with 2 × IDC10 plugs + a housing with a holder for mounting on a DIN rail.
