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 =2.2k Ω with
V
CC
= 24V ±5%
R1 =1k Ω with
V
CC
= 12V ±5%
R1 =180 Ω with
V
CC
= 5V ±5%

Open-collector Output, Example 2: Using a servo amplifier with an
internal 12V power supply
This circuit uses the 12V 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 or open-
collector transistor circuit. Select a low-current relay; otherwise a faulty
contact will result.
