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.<\/p>\n
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.<\/p>\n
Full bridge rectification allows the board to operate from a compatible 12V AC or 12V DC source. Confirm the supply voltage before connection.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
The onboard LED shows when the relay circuit is active, helping with setup and fault checks.<\/p>\n
The common contact is potentially free, allowing the relay to switch a separate compatible circuit without directly carrying the trigger voltage into that circuit.<\/p>\n
Buy the Sherlotronics 12V AC\/DC relay board from Patsec Security Store at Accra Road, White Angle House, first floor, shop 76, Nairobi. Provide the devices and voltages being connected so suitability can be checked.<\/p>\n","protected":false},"excerpt":{"rendered":"
