PTA - The PTA converts a single pulse-width modulated input to an analog current or voltage output.  A timed contact or solid state closure from the controlling microprocessor controller is converted to a linear analog output signal with 256 steps of resolution. The last output signal is held until the PTA receives the end of the next pulsed input signal. The PTA's output will not wrap around if an excessively long input pulse is received. Ten preset analog output signal spans are DIP switch selectable. In addition the span and offset potentiometer offer maximum user adjustment of the output signal. The input signal is optically isolated and can accept either positive or negative polarity.  The PTA is covered by ACI's Two (2) Year Limited Warranty.

PTA2 - The PTA2 accepts a timed contac or solid state closur from a microprocessor controller and converts it to a linear analog output with 255 steps of resolution.  The PTA2 will not wrap around if an excessively long pulse is received. Four input pulse rates are jumper selectable. The input signal is optically isolated and can accept either positive or negative polarity. The PTA2 includes triac adapter circuitry ( jumper selectable) for a triac input. The PTA2 has a jumper selectable manual override which will allow modulation of the output between 0-10VDC to verify proper operation of the controlled device.  The last output signal is held until the PTA2 receives the end of the next pulsed input signal.  The PTA2 is covered by ACI's Two (2) Year Limited Warranty.
