External Input Signals
The PL’s RAS interface connector uses the following input signals.
‹
General Purpose Signal Input (DIN 4 bits)
This standard digital input is used for alarm detection in external devices. The input signal uses four bits.
The System Monitor property of the control panel or the API-DLL can be used to enable or disable this
feature, as well as designate what type of processing is to be performed once a signal is received. (Only the
“ON” state of the DIN circuit is detected. The “OFF” state of the DIN circuit cannot be monitored.)
‹
Remote Reset Input
This is the reset signal sent from an external device to the PL. When this signal is enabled, a forced reset of the
PL is performed.
The System Monitor property of the control panel or the API-DLL can be used to enable or disable this feature.
Input Voltage DC12V to DC24V
Input Current 7mA
Operating Voltage ON voltage: 9V (min), OFF voltage:3V (max)
Isolation Method Via photocoupler
• General Purpose Signal Input (DIN) level must be 1.5S or longer to be detected.
• Be sure the voltage value between terminals is controlled via the input voltage, so
that the PL is operated within its recommended range. If the input voltage exceeds
this range, a malfunction or PL damage may occur.
• With Sink/Source input, even if the D(-), and RESET(-) are positive, and D(+),
RESET(+) are negative, no problems are created. Be sure to operate the unit within
the recommended voltage range.
