Pulse Digital input converting to 0-10v control output

The IO/PDV is designed to convert pulsed modulating control to an analogue voltage based output of 0-10 volts. The output time base is adjustable to enable connection to controllers with a fixed pulsed modulating control.

The 2 x digital inputs can be volt free contacts or triac switched (20 to 50 volts AC) when auxiliary supply is selected.

The IO/PDV output is directly proportional to the time base of the input signal making it suitable for preset positioning of dampers in VAV applications.
