APS-1102 Programmable AC/DC Power Source 4-47
4.5 Control Using External Control I/O Connector
Digital signals that are input to the external control I/O connector can be used to control sequences and the
output on/off setting. The sequence step synchronized output signals are output from the external control
I/O connector.
The status of the APS-1102 can be monitored by reading the output signals from the external control
input/output connector.
See “3.3.4 External signal input/external sync signal input terminal”.
After the external signal input level was changed, approx. 50ms might be required for the controller to
execute a function as a maximum response time. “Output ON/OFF” additionally requires the similar time
for a response of a relay device.
Table 4-13 lists the functions of the connector various pins.
