$45.54
The Model PWA-1A Pulse-to-Analog Transducer convertsa DIP switch selectable pulse-width modulation(PWM) input to 0-18V and 0-20 mA outputs (factory setfor 1-5V and 4-20 mA). Using the multiplex mode, up toeight units can be controlled from one BAS controlleroutput. The Model PWA-1A is furnished in a uniqueslim-line design housing, which saves panel space, andcan be ordered with an optional DIN rail mountingadapter. The Model PWA-2A is a snap-track mountedversion of the pulse to analog transducer, and its operationis identical to the Model PWA-1A.The Model PWA-1T Tri-State-to-Analog Transducerconverts two contact closure inputs (tri-state/floatingcontrol) to 0-18V and 0-20 mA outputs (factory set for1-5V and 4-20 mA). It is mounted in a unique slim-linedesign housing, which saves panel space, and can beordered with an optional DIN rail mounting adapter. TheModel PWA-2T is the snap-track mounted version ofthe tri-state to analog transducer, and its operation isidentical to the Model PWA-1T.On all models, the outputs are zero and span adjustablefor a wide variety of ranges (factory set for 4-20 mAand 1-5V). Current and voltage outputs are active simultaneously.After a power failure, a memory featureon all models allows their outputs to return to their lastvalues before power was interrupted and remain thereuntil a new signal is received. (Memory feature may bedisabled by user if desired.)Features- 255-step resolution in any range
