TR PROVEN PCB TIME DELAY RELAY WITH ADJUSTABLE TIME-ON OR TIME-OFF DELAY OR PULSE RELAY TR-RELAYS * Not susceptable to external disturbance. * Increase in timing range by using an external capacitor with time-off delay device - o -. * No first cycle effect", with the time-on delay device. The first and following operations are of the same duration.

This must be replaced by an external potentiometer. The time delay thus achievable is 20s per 100 k with the -i- devices and approx 20s per 1 M with the -o- devices. The minimum time delays are 1s (with -i-) and 0.1 s (with -o-). * With the -o- 0s device, the pulse frequency is 5 Hz. max., and is inversely proportional to Rext (e.g. at 20 k the pulse frequency is 1 Hz).
