Fixed Timing Relays

	Description
	Bulletin 700-HTF Fixed Timing Relays feature a plug-in tube base. Construction is the same as the Bulletin 700-HT relay except that the adjustment knob has been removed to help prevent unwanted tampering. The timing and output specifications are identical to those of the Bulletin 700-HT relay. Setting time will be ±5% of the time ordered. Socket: Cat. No. 700-HN100 or 700-HN125 (On-Delay) Cat. No. 700-HN101 or 700-HN126 (Off-Delay)

¬ Use both the Timing Value and Timing Units tables to properly select the desired fixed time relay.
For example: 700-HTF22025SU24 selects a timer value of 2.5 seconds and 700-HTF22025MU24 selects a timer value of 2.5 minutes.

Trigger Signal Cat. Nos. 700-HT / -HS

Contact closure provides signal to timer. A low energy signal is generated by the 700-HT / -HS timing relay. For optimum reliability, use contacts designed for low energy switching (10V, 1 mA) (Bul. 800F-X__V, 800T-X__V). No external voltage should be connected to the contact signal.
