‹ External Output Signal
The PS-A’s RAS interface connector uses the following output signals.
• General-Purpose Output (DOUT 2 bits)
This general purpose digital output signal provides system condition information to external devices.
The System Monitor property of the control panel or the API-DLL is used by applications to control this signal.
The above mentioned general purpose digital output signals provide system condition information to
external devices.
The System Monitor property can be used to enable or disable any of these output signals.
• 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 is operated within its recommended range. If the input voltage
exceeds this range, a malfunction or PS-A 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.
