Figure 3: DPC 8-pin mini-din connector confi guration
CAUTION: 4-20 mA analog output requires at least 14 Vdc power.
CAUTION: Generally, "Mini-DIN" Connector numbering patterns are
standardized. There are, however, some connectors with nonconforming
patterns, so the numbering sequence on your mating connector may or may
not coincide with that shown in our pin confi guration above. It is imperative
that you match the appropriate wires in accordance with the correct sequence
regardless of the particular numbers displayed on the mating connector.
3.1 Power Supply Connections
The AC to DC power supply requirements for DPC04/07/14/17/37/47 controllers are 12 to
26 Vdc, with maximum load current at least 350 mA (unipolar power supply), and maximum
ripple below 150 mV P-P. The AC to DC power supply requirements for DPC57/67/77
controllers are 24 to 26 Vdc, with maximum load current at least 650 mA (unipolar power
supply), and maximum ripple below 150 mV P-P.
Power can be applied to the DPC controller either through the power jack or the 8-pin Mini-
DIN connector (see Figure 1).
CAUTION: Never apply power simultaneously from both connectors, as this
may damage the instrument.
DC Power (+) --------------- pin 7 of the 8-pin Mini-DIN connector
DC Power (-) --------------- pin 8 of the 8-pin Mini-DIN connector
CAUTION: Never apply power voltage above 26Vdc. Doing so may damage the
DPC and/or cause faulty operation.
