Plug-In Delay On Break Timers - TNM Timers
Plug-In Delay On Break Timers
The TNM Delay on Break units meet the needs of customers who require IC digital timing circuits with octal, magnal round and QC bases for plug-in installation. The units are available in SPDT, DPST and DPDT relay forms up to 10 amp with fixed or adjustable time periods.
Input voltage is applied continuously. Upon closure of the normally open isolated external initiate switch, the load is energized, and remains energized as long as it is closed. When the external initiate switch opens, the time delay is started. At the end of the time delay, the load is de-energized, and the timer is ready for another cycle.

|BASIC WIRING AND DIMENSIONS
- VAC: 12, 24, 120,230,50/60/ Hz
- VDC: 12 or 24
Relay Contact Ratings: 5 amp DPDT, 10 amp DPDT Optional
Repeat Accuracy: ±0.1% under fixed operating conditions
Reset Time: 50 milliseconds
Tolerances: Fixed: ±10%, Optional: ±5%, ±1% Variable: +20%, -0 Optional:+10%, -0%
Note: Tolerances on variable units are with respect to
upper limit only. Timers with time periods greater than 10 sec. will have a 100 to 1 ratio, i.e., 1 to 100 seconds, 30 to
3000 seconds. Timers with time periods less than 10 sec. will have a 10 to 1 ratio, i.e., .99 to 9.9 seconds, .5 to 5 seconds.
