Configuration of PLC Interfaces for PL Series





The PLC system is used with and external PLC controller, PLC indexer card, or other device in positioning applications. The input connector supports controller input signals and the Limit Loop safety.

The PLC series supports 4 types of interfaces:
1. PD Sinking Style (SN). The PD SN is for +5V interfaces in which the PLC will sink the output signals (step & direction) to ground when active. The P1-4 pin of the connector will source +5V supply for the PLC card and the optical interface.

2. PB Sourcing Style (SO). The PB SO is for +5V interfaces in which the PLC will source the output signals (step & direction) to +5V when active. . The P1-4 pin of the connector will source +5V supply for the PLC card and the optical interface.

3. PL Sinking Style (SN). The PL SN is for +24V interfaces in which the PLC will sink the output signals (step & direction) to ground. The P1-4 pin of the connector must be connected to the source of +24V for the optical interface.

4. PL Sourcing Style (SO). The PL SO is for +24V interfaces in which the PLC will source the output signals (step & direction) to +24V. The P1-1 pin of the connector must be connected to the return (ground) of the source of the 24V for the optical interface.
