12Vdc powered 0.1 second to 4 minute non-retriggerable delayed-off timer board module with mains rated relay output. When activated the relay turns on for the user-set time period and then turns off.
The timer is triggered by closing the Start Input (using for example a volt-free push button or relay contact closure).
This is a non-retriggerable timer - the relay will always turn off at timeout. Any further Start Input triggers received during countdown or it being in an open or closed state at timeout are ignored. The timer resets on timeout and is ready for a new trigger. The Start Input must go open circuit and be closed again to register a new trigger input.
An optional INSTANT-ON mode disables the start input. In this mode, the the relay turns on and the delay countdown commences immediately power is applied to the board. The relay turns off when the user-set time delay time has elapsed. Power must be removed and reapplied for a fresh countdown to commence. Instant-On mode is set using a header jumper.
Scale switch selects one of two delay ranges, 0.1 to 24 seconds or 1 second to 4 minutes, giving more precise and easier time setting using the onboard potentiometer (header pins allow the use of user-supplied external potentiometers if required).
An LED indicates that the relay is active. The board is reverse polarity protected.
2023 Product Update: New improved DIN-Rail size board with wider time range and easier setting.
