Trigger

DP900 series power supply supports trigger input and trigger output via the rear-

panel Digital I/O interface (optional for DP932U and not available for DP932E).

• Trigger Input:

The data lines of the digital I/O interface receive external trigger signal. The

source under control (namely the selected output channel) turns on/off the

output or inverts the output state when the preset trigger condition is met.

• Trigger Output:

The data lines of the digital I/O interface output a high/low level signal when the

control source (namely the selected output channel) turns on the output.

The 4 data lines of the digital I/O interface are mutually independent and can be used

for trigger input or trigger output separately.

The digital port connections are shown in the figure below.
