„ General-Purpose Input (DIN 0, 1)
„ RAS Input Start
RAS Input Start
*1 *2
is a function which allows input to DIN1(+) to start the PS-A unit from Hibernate or Soft
OFF state.
After the input start, DIN1(+) can be used as General-Purpose Input.
Input signal electric specifications is the same as General-Purpose Input
Input Voltage DC12V to 24V
Input Method Sink / Source Input
Input Current 10mA (DC24V)
Input Resistance 3.6k
Ω
Input Points 2 points (common with external reset input)
Operation Range
ON voltage DC10V or more
OFF voltage DC3V or less
Isolation Method Photocoupler Isolation
Dielectric Strength Voltage 500V or more
• General-Purpose Input (DIN) level must be 1.5 seconds or longer to be detected.
It may not detect under 1.5 seconds.
• Be sure the voltage value between terminals is controlled via the input voltage, so
that the PS-A unit is operated within its recommended range. If the input voltage
exceeds this range, a malfunction or PS-A unit damage may occur.
• The Sink/Source input can be used even if the DIN(-), and RESET(-) are positive,
and DIN(+), RESET(+) are negative. Be sure to operate the unit within the
recommended voltage range.
*1 To use RAS Input Start, set System Set SW 2 No.3 to ON. See "2.4 DIP Switches (page 2-14)" for DIP
Switches details.
*2 Available only for RAS port type.
• PS-A unit will be restarted if you shut down Windows
®
during DIN(+) input. To
change PS-A unit to Soft OFF state, set DIN1(+) input OFF before shutting down
Windows
