CAUTION!
THE I/O CONNECTOR SIGNALS ARE ELECTRO-
STATICALLY SENSITIVE AND SHALL BE HANDLED ONLY
IN AN ESD PROTECTED ENVIRONMENT.
Remarks:
3. The 24V opto-isolated I/O signals are referenced to the isolated ground 0VPLC, which
shall be common to all the devices sharing these signals.
4. The 24V opto-isolated inputs have a typical threshold of 8 Volts, therefore will not accept
TTL levels.
5. The isolated 24VPLC supply is required only for operation of the outputs. Hence, if your
application uses only opto-isolated inputs, the 24VPLC supply connection is not
necessary.
6. The inputs IN#37/D and IN#38/P accept both TTL (5V) and 24V signals and are opto-
isolated. These inputs are referenced to the drive logic ground GND
