Simple din rail mounted or 8 & 11 pin plug in dedicated delay off via a leading edge trigger input timer, with dedicated coil voltage and time range. The timers are SPCO output with a DPCO option for an 11 pin plug in. A choice of one of three multi time ranges can be requested. The timers feature a red LED to indicate relay output status. All terminal details along with the CE mark is clearly marked on the sides of the housing.
A permanent supply is required at all times on to the coil terminals, however this is not the controlling factor. The controlling factor is a trigger input S2, on S2 closing the relay contacts energise and timing immediately commences (leading edge), after the set delay time the contacts de-energise. If the coil supply is removed during the timing period the contacts immediately de-energise. If the trigger input S2 is present before the connection of the coil supply, the contacts will not energise, the coil supply has to be present before the timer sees the leading edge of the trigger input. If S2 is initiated again during timing this will have no effect, timing has to be completed before another leading edge of the trigger takes effect.
The command contact S2 should be isolated from other circuits and must only be connected to the same supply as the coil voltage to the timer. If this cannot be achieved, use UNI-1M or UNI-4M or 8/11 pin plug in units.
