INPUT/OUTPUT SIGNALS

PAGE

Input/output signals

The p400’s input/output signals are divided into three categories: auxiliary DC power, input signals, and

output signals. Signals in each category are fully described in the following sections.

Auxiliary DC power

P400 User I/O connector provides auxiliary DC power for driving external inputs or outputs connected

to the User I/O port. Pin 4, +5 VDC Auxiliary Power, and Pin 5, +24 VDC Auxiliary Power, are protected

by self-resetting fuses rated at 0.5 A. Pin 12, Auxiliary DC Power Ground, is connected to chassis ground

while all other User I/O pins are floating with respect to chassis ground. The figure below illustrates

P400’s internal DC supply wiring.

Figure 4-23 Auxiliary DC power diagram.
