10 Wiring and Installation
Figure 6: PNP Configuration: This configuration is the most popular for open collector
PNP outputs.

Figure 8: Open Collector Outputs to D8 Inputs with Input Common Connected to ground.
For 24VDC power, the pull-up resistor should be a 4.7kΩ, ¼ watt resister. The output
must be capable of switching 2.6mA when closed. When the open collector output is
open, the DI/O input sees 11.8V @ 2.6mA.
For 12VDC power, the pull-up resistor should be a 1 kΩ, ¼ watt resister. The output must
be capable of switching 2.6mA when closed. When the open collector output is open, the
DI/O input sees 9.4V @ 2.6mA.
10.2.11. Q1 Wiring
The Q1 expansion module can be wired to quadrature encoders.
Use shielded twisted pairs for all connections to inputs and outputs. Route the encoder wiring
separate from other wiring. You must provide the power supplies needed by your encoders.
See Wiring Guidelines for general wiring information.
Wire clamp screws must be tightened to max 7 b-in (0.8Nm).
NOTE:
The example schematics do not include transducer pin numbers, color codes, or power supply
requirements, since these vary between different transducers. To determine your power
