Installation 2-23
A resistor can be connected in series with the circuit shown in order to restrict
the inrush current.
Figure 2.24 Limitation of the inrush current with a resistor
Connecting DC Inputs
Use input terminals I1 to I12 to connect push button actuators, switches or 3
or 4-wire proximity switches. Given the high residual current, do not use
2-wire proximity switches.
Input signal voltage range
I1 to I6, I9, I10
OFF signal: 0V dc to 5V dc
ON signal: 15V dc to 28.8V dc
I7, I8, I11, I12
OFF signal: < 8V dc
ON signal: > 8V dc
Input current
I1 to I6, I9, I10, R1 to R12: 3.3 mA at 24V dc
I7, I8, I11, I12: 2.2 mA at 24V dc
IMPORTANT
When using a 100 nF capacitor, the drop-out time of the
input increases by 80 (66.6) ms at 50 (60) Hz.
