R, 2 R47 4-200 2 es) Ser R471, R472 (2364-200 Series) Pneumatic-Electric Switches The pneumatic-electric switches are used in control systems requiring conversion of gradual air pressure changes to positive electrical switching actions. The R471-1 has a single SPDT switch for switching a single circuit. The R472-1 has two SPDT switches for switching two separate circuits simultaneously. Features: • Fixed-differential P.E. switches permit two-position electrical switching action from either modulating or two-position pneumatic signals. • High current rating: 20 amps non-inductive, 120, 240, 480Vac. • R471-1 has one SPDT switch. • R472-1 has two SPDT switches which operate simultaneously. • May be wall-mounted or panel-mounted where necessary to keep wiring runs short.
