AC Power ON/OFF Control
The power protection device (AC power relay) can be controlled on
/off from an external signal (provided that the power switch is on).
CV/CC Monitoring
●
A monitoring output from about 0 V to 1/10 the rated voltage
can be output with respect to the output voltage from 0 V to the
rated voltage.
●
A monitoring output from about 0 V to 10 V can be output with
respect to the output current from 0 A to the rated current.
Control by an External resistance of Output Voltage and Current
61
Remote Sensing
This function prevents the voltage
drop which is caused by the load
connection resistance and the
stability degradation caused by the
contact resistance, and compensates
for the voltage drop of up to 1 V
per path provided that the output
terminal voltage is within the rated
voltage.
Output ON/OFF Control
The output can be turned on/off with
an external signal. The output can also
be fixed to on while power is on.

*
Each of the Floating (Common) input/output signals passes through a photo coupler and uses a diode input and open collector output. Their common
terminal is common.
* The alarm signal is also output during the operation of the input current protection circuit or input over-voltage protection circuit.
