14. External control
14.1
●
Control by REMOTE/OUT connector
By means of the
REMOTE/OUT
connector
⑱
on the rear panel, the remote control of
start/stop, the setting of interlock to secure the safety, and the output signals corresponding
to each condition of the
8526
can be output by open collector.
The input and output signals are isolated from the internal circuit by photo-coupler.
Also, the
8526 is provided with the power source of 24V DC 0.1A, which can be utilized
as power supply for the external control.
