Sherlotronics Relay Board 12 Volts AC/DC

Description

Sherlotronics 12V Relay Board Price in Kenya

The current price is KSh 450. This relay board accepts a 12V AC or DC control supply and provides normally open, normally closed and common contacts.

What Is a 12V Relay Board?

A relay board lets a low-voltage control signal switch or isolate another electrical circuit. It is commonly used between alarm, electric-fence and access-control equipment.

12V AC and DC Input

Full bridge rectification allows the board to operate from a compatible 12V AC or 12V DC source. Confirm the supply voltage before connection.

Normally Open and Normally Closed Contacts

The relay provides normally open and normally closed outputs with a common contact. These terminals allow an installer to change the switching behaviour required by the connected equipment.

Converting NC Contacts to NO

The board can convert a normally closed trigger into a normally open output, or vice versa, where compatible alarm and control devices require different contact logic.

Isolating Electric-Fence Energizer Outputs

Relay isolation can protect a sensitive transmitter or alarm input from direct connection to an electric-fence energizer output. Wiring must follow the ratings and instructions for both devices.

Switching Sirens, Strobes and Lights

The relay may be used to control compatible sirens, strobe lights and higher-voltage lighting circuits. Do not exceed the relay contact rating, and use a qualified installer for mains-voltage wiring.

LED Status Indication

The onboard LED shows when the relay circuit is active, helping with setup and fault checks.

Potential-Free Common Contact

The common contact is potentially free, allowing the relay to switch a separate compatible circuit without directly carrying the trigger voltage into that circuit.

Products Often Used with the Relay Board

Common pairings include the alarm siren kit, the Sherlotronics 12V timer module and the RX4-500 receiver. Mount it in a waterproof adaptor box outdoors.
