Applications
The “single-channel p/Q controller card” consists of the basic
card in standard Europe format together with DC/DC converter
and front plate. The “2-channel p/Q controller card” version
consists of this same basic card equipped with an additional p/Q
daughter card incorporating the same circuitry. The two cards
share a common front plate.
The supply voltage is 24 V DC. This card does not provide the
power supply for the valve being regulated.
The input parameters for the cards comprise the setpoint value
for valve position, the setpoint value for pressure, the actual
(feedback) pressure and any control mode signals. The pressure
sensors with voltage interface receive their voltage supply from
the card (z6/z8).
Cards are for the connection of pressure sensors with both
voltage and current signals.
The setpoint value for pressure is selected via potentiometer.
The potentiometers can be supplied from the card (z32/b12).
Test connections in the front plate and on the card are available
for monitoring and compensation tuning of the most important
parameters.
The circuitry of the “2-channel card” is designed to allow fully
independent operation of the controller on the basic card
and that on the daughter card. In this mode, the card can be
employed to control 2 valves with on-board electronics
(see example 2).
An additional channel mode circuit provides a substantial
increase in the range of optional applications for these cards
(see example 1).
