Analog Input ATP (Analog to PWM Output)

ATP-R converts an analog signal into a digital pulse output signal. The user can select eight standard analog input ranges to the ATP by changing jumper shunt positions. To select the output pulse range, the ATP has an eight position DIP switch. The output pulse is continuous with a one second off between pulses. ATP-R Version 2 operates the same except no pulse output occurs when the analog input falls to, or below 10% of the input signal range.  This allows for a true "OFF" setting for solid state relays controlling electric heat. The ATP-T is a Triac Output (24VAC only).  You need to contact ACI for technical asistance when ordering.  ATP-Y is a also a Form C Relay Output (24VAC or VDC) with an option of two pulse ouput ranges designed to communicate with York(TM) Chiller Control Packages.  Some chiller control panels require a 1-11 or 0-21 second pulse to remotely reset chilled water temperatures.  Specify one of two pulse ranges when ordering.  The ATP is covered by ACI's Two (2) Year Limited Warranty.
