Chapter 3 PL Monitoring Features

 External Output Signal

The PL’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.

• 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 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.
