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)
