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

Note:
Excitation voltage ripple should be maintained below 5% by use of appropriate smoothing.
Strong external magnetic fields influence relay data.
1) Data concerning operational life is based on resistive loads and ambient temperature of 20-30°C.

Operation
+ The trimmer is omitted on the -i/-o- 0s device.
This must be replaced by an external potentiometer. The time
delay thus achievable is 20s per 100 kΩΩwith the -i- devices
and approx 20s per 1 MΩΩwith 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 kΩΩthe pulse
frequency is 1 Hz).
