Relay Boards

Easy to fit and wire for additional control functions or to expand the capability of existing relay outputs, these simple boards contains either one or four 24V DC relays, which can be used for any extra-low voltage switching applications.

Each relay has two changeover contacts, and an LED indicator to show when the coil is energised. The coils of the relays are common to the positive supply and the relays can be operated individually by switching a negative to the numbered coil inputs.

The contacts are suitable for switching a maximum of 30V DC and 2 Amps. The current consumption of the unit when operated from a 24V supply is approximately 25mA per relay.

4 Way Relay Unit

Housed in a robust sheet steel enclosure, the 4-Way Relay Unit features 4 pairs of 240V AC mains rated relay contacts that can be operated using switch negative signals from up to 4 control panels.

Isolate switches and status LED’s are provided for each relay.
