The appearance of option -J and -J1 models are defferent from
the of standard appearance. Please contact us about the detail.

Oil and other chemical liquid splashing environment may cause
the performance degradation and failure.
¿
-R
-
You can control output ON/OFF remotely in Option -R models.
To do so, connect an external DC power supply and apply a
voltage to a remote ON/OFF connector, which is available as
option.

1 If the output of an external power supply is within the range
of 4.5 - 12.5V, you do not need a current limiting resistor R. If
the output exceeds 12.5V, however, please connect the cur-
rent limiting resistor R.
To calculate a current limiting resistance value, please use the fol-
lowing equation.
