Reaction Time:
• < 20 ms
(*)
•
Tripping time of the External Protection in case
of a cold restart:
≤ 0.5 s
(*)
The reaction times have been measured with a WIC1 that is ready to trip (i. e. green Ready
LED is lit). They are the time-span for the External Protection from activation of the trigger
signal until activation of the “TC+/−” impulse output.

Digital Inputs (WIC1‑4)
A device of type WIC1‑4 can feature 2 Digital Inputs (depending on the order option). For
variants WIC1-4xxxxF there is a 󰊟xed assignment to “External Trip” and “External Reset”,
respectively. For variants WIC1-4xxxxC, this is a default assignment that can be re-de󰊟ned.
The Digital Inputs are not potential-free, i. e. they are not isolated from the housing and
from the internal electronics. Moreover, the two Digital Inputs of the WIC14 are grouped, i. e.
share a common electrical potential.
The input voltage range can be selected by software parametrization.
