External Output Signal
The PL unit’s RAS interface connector uses the following output signals.
‹ ‹ ‹ ‹ ‹
General Purpose Signal Output (DOUT)
This general purpose digital output signal provides system condition information to
external devices.
The System Monitor’s API-DLL are used by applications to control this signal.
‹ ‹
‹ ‹ ‹
Alarm Output (1 point)
‹ ‹ ‹ ‹ ‹
Lamp Output (1 point)
The above mentioned general purpose digital output signals provide system condition
information to external devices.
The System Monitor utility can be used to enable or disable any of these output signals.
Also, when Alarm Output is enabled, the indicator is always lit orange.

• Be sure to operate the unit within its maximum load current. If
the maximum load current exceeds this range, a malfunction or
PL damage may occur.
• Design your electrical system by adding the load current and
voltage values to the terminal voltage. If load current value used
is large, a maximum voltage of 1.5V will exist between the terminals.
• When connecting an induction load, be sure to connect the
above drawing's protection diode(*1).
Rated Load Voltage DC12V to DC24V
Maximum Load Current 100mA/point
Maximum Voltage Drop between Terminals 1.5V (at 100mA load current)
Isolation Method Via photocoupler
