For decades, timing functions have been provided through the use of either thermal of mechanical timers. Thermal timers provided only marginal accuracy and mechanical timers were high maintenance items. Now US&S has combined the reliability of solid state electronics with quartz accuracy to produce a highly flexible general purpose solidstate timer: The PN-150EVT.
US&S has expanded the PN-150EVT line to include a slow drop solid state programmable timer and a delayed pick-up, slow-drop version.
PN-150EVT
The PN-150EVT Solid-State Timer is a programmable timer relay that applies quartz accuracy to timing functions. This timer provides a slow pick function that is field adjustable from 0.3 seconds to 59 minutes 59 seconds. Between 0.3 seconds and 59.9 seconds, the time is adjustable in 0.1 second increments. Between one minute and 59 minutes 59 seconds, the time is adjustable in 1 second increments. The PT -150EVT timer mounts in the same manner as a conventional PN-150 relay, and when mated with an optional adapter base, it is a direct replacement for the PT-55 mechanical time element relay.
PN-150EVT-SD
The PN-150EVT-SD slow-drop electronic timer and the PN-150EVT-DPSD delayed pick-up slow-drop electronic timer are based on the original PN-150EVT design, upgraded with new software to provide an adjustable drop-away time. This timer features a programmable slow-drop function that is field adjustable from 0.0 seconds to 59 minutes, 59 seconds. The drop- away time is adjustable in 0.1 - second increments between an interval of 0.0 seconds and 59.9 seconds. The time is adjustable in 1-second increments between the interval of 1 minute-and 59 minutes, 59 seconds. PN-15OEVT Solid State Timer
PN-150EVT-DPSD
The PN-150EVT-DPSD timer features a five-second delayed pick-up and a programmable slow-drop function, which can be field adjusted for the same periods specified for the PN-150EVT-SD timer above.
