The following examples show how to select the pull-up resistor R1 so the
input current (I) falls between 7 and 15mA.
Application Examples
R1 = 2.2 kΩ with
V
CC
= 24 V ±5%
R1 = 1 kΩ with
V
CC
= 12 V ±5%
R1 = 180 Ω with
V
CC
= 5 V ±5%
• Open-collector Output, Example 2: Using a servo amplifier with an
internal 12 V power supply
This circuit uses the 12 V power supply built into the servo amplifier.
The input is not isolated in this case.

„ Sequence Input Circuit Interface
The sequence input circuit interface connects through a relay, open-
collector transistor or NPN sensor circuit. Select a low-current relay;
otherwise a faulty contact will result.
