3-4-3 Applications for Different Output Encoders
1. Open collector output encoder application: Use one pull-up resistor for each set of input current 5–
15 mA. If open collector input voltage uses 12V power, connect the encoder power externally. See
the PG wiring Figure 3-13 below.
Power supply switch for frequency division. Switch to INP to provide 24V
power for internal use. Switch to EXP to provide 24V power for external use
(client).
5 V Suggested pull-up resistor: above 150–520 ohm, 1/2 W
12 V Suggested pull-up resistor: above 600–2K ohm, 1/2 W
