The PS57 is a combination power supply and 4 1/2 digit LED display for the P55/P855 family of pressure transducers and transmitters. The PS57 accepts 110 VAC power and provides the required 24 Vdc excitation for the transducer. The transducer signal is received and displayed directly in engineering units with bright 0.56″ high red LEDs. The user can re-scale the display and set the decimal point by configuring internal jumpers. The analog output of the transducer, ± 5 Vdc or 4-20 mA, is available on rear-panel terminals.
The PS57 is available in ± 5 Vdc versions and 4-20 mA versions, depending on the P55/P855/P56 version ordered. A special accessory cable connects the PS57 to the transducer – no soldering or external wiring is needed. The PS57 fits in a standard 1/16 DIN cut-out for control panels up to 2 inches thick.
The PS57 will be scaled at the factory when ordered in conjunction with transducers or transmitters.
