12V 10A Changeover relay that operates on a +12V input signal and has an adjustable delay time that the user can configure to meet the requirements of their application.
The relay operates in one of two modes:
DELAY OFF – When a momentary input is received, the relay will switch on and will remain on until the input is removed at which point the relay will begin the countdown to switch off. If no further input is received the relay will switch off after the set timescale. Note: If a feed is received during the countdown period the timer begins again.
DELAY ON – When a continuous input is given the countdown to switching on begins, if the input is not removed then the relay will switch on after the desired timescale, upon removal of the input feed the relay will switch off.
The relay is fully time adjustable from 0.5 seconds - 6 hours making this relay extremely versatile and suitable for most applications.
Adjustment is made by removing the plastic plugs on top of the relay to access the dials beneath.
Full Adjustment details are included in the package
Timer Settings Adjustment is made by removing the two plastic blanking plugs on the top of the relay, the dial labelled 0-9 controls the desired relay state and timescale as listed in the table included, the plain screw dial controls the timeframe that the relay stays on or off for.
Fully anti-clockwise = minimum time setting. Fully clockwise = maximum time setting
Important: If the intended load draws more than 10A then this relay should not be used to directly switch the load. In this case the output should be used to switch the coil of a secondary relay that has a sufficient current rating and is fitted with a voltage suppression resistor or diode, this voltage suppression is important to prevent voltage spikes damaging the timer relay electronics.
Please note that due to the internals used in this relay it is not possible to use it to switch the negative side of the circuit.
