PTA2 | Pulse Width (PWM) Input to Analog Output Interface Module

Description

The PTA2 accepts a timed contact, or solid state closure, 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. Seven input pulse rates are jumper selectable (between Version 1 and 2). 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 0-10 VDC to verify proper operation of the controlled device. On Version 1, the last output signal is held until the PTA2 receives the end of the next pulsed input signal.
