PRESSURE CONTROLLER operating manual

Power and Signal Connections
Power can be supplied to your controller through either the power jack or
the multi-pin connector on top of your device, depending on configuration.
✓
Note:
Controller power jacks require a 12–30 Vdc power supply
with a 2.1 mm female positive-center plug capable of supplying
at least 250 mA, with an additional 40 mA for a color display.
4–20 mA analog outputs require at least 15 Vdc and 290 mA.
✓
Note:
Large valve controllers (PCR models) require a
24–30 Vdc power supply with a 2.1 mm female positive-
center plug capable of supplying at least 750 mA.
Standard 8-Pin Mini-DIN Pinout

Caution:
Do not connect power to pins 1 through 6
. Permanent
damage can occur. Pin 2 (5.12 Vdc Output) is often mistaken
for the standard 0–5 Vdc analog output signal. Pin 2 is
normally a constant 5.12 Vdc that reflects system bus voltage.
