Schneider Electric's Square D 9050HO-1D Pneumatic Timing Relay is a compact timer in the 9050 family used to add timed sequencing to industrial control circuits. The device uses a timing head and magnet assembly housed in a mounting base to deliver controlled on-delay or off-delay outputs, with the timing mode changeable by rotating the magnet assembly. The 9050 family supports SPDT and DPDT timing contacts, and typical timing ranges for these pneumatic timers span from 0.1 seconds to 60 seconds, enabling precise, mechanical-delay control in panels and equipment where electronic timers are not required or preferred.
