2.5.1.4 Increased input current
The following input circuit can be used in order to prevent interference and
also when using two-wire proximity switches:
Figure 15: Increased input current
A resistor can be connected in series with the circuit shown in order to
restrict the inrush current.
Figure 16: Limitation of the input current through resistors
Complete devices for increasing the input current are available under the part
no. EASY256-HCI.
Figure 17: easy with EASY256-HCI
￫
When using a 100 nF capacitor, the drop-out time of the input
increases by 80 (66.6) ms at 50 (60) Hz.
￫
The increased capacitance increases the drop-off time by approx.
40 ms.
