The HP50B6 CYCL-FLEX reset timers are electric reset time controllers manufactured by Eagle Signal, a Danaher Speciality Products company. The HP5 series timers are high quality, synchronous motor driven reset timers housed in the standard CYCL-FLEX plug-in housing. The HP50B6 timer has a time range of 30 seconds, has a minimum setting of 1 second and has a progress pointer to let you know how far along it is. The calibrated dials are highly visible and are 7.85 inches (19.939 cm) in circumference providing easily read and well spaced calibrations. The progress pointer is red and displays the remaining time interval. On the HP50B6, Eagle Signal included a pilot light that points out when the timing motor is energized. This timer runs off of 240 VAC. There is an additional option which runs on 120 VAC. For this option, please see HP50A6. The CYCL-FLEX housings have 15 terminal ABS (UL rated 94V-0) molded housing with high impact resistance and will not support combustion.
