Pulse / Tri-State-to-Analog Transducers

Order Now Order Now!
The PWA-1A pulse-to-analog transducer converts a DIP switch selectable pulse-width modulation (PWM) input to 0-18V and 0-20 mA outputs (factory set for 1-5V and 4-20 mA). The PWA-1A is furnished in a unique slim-line design housing, which saves panel space, and can be ordered with an optional DIN rail mounting adapter. The PWA-2A is a snap-track mounted version of the PWA-1A.The PWA-1T tri-state-to-analog transducer converts two contact closure inputs (tri-state/floating control) to 0-18V and 0-20 mA outputs (factory set for 1-5V and 4-20 mA). It is mounted in a unique slim-line design housing, which saves panel space, and can be ordered with an optional DIN rail mounting adapter. The PWA-2T is the snap-track mounted version of the PWA-1T.On all models, the outputs are zero and span adjustable for a wide variety of ranges (factory set for 4-20 mA and 1-5 V). Current and voltage outputs are active simultaneously.
