Terminal Assignment for Digital Inputs
DC voltage signals or AC voltage signals can be processed via the digital
inputs. The Excel 100C has twelve digital inputs.
From 5 V input voltage upwards, the digital signal is set to status 1. With a
hysteresis of 2.5 V, the digital signal must fall below 2.5 V so that the
digital status 0 is transmitted (R
i
= 15 kΩ).
IMPORTANT
Line voltage must not be present at any of the terminals under any circumstances. Devices with 110 V/230 Vac must be isolated
by a transformer.
Six additional digital inputs are available at the terminals 49 to 54 for switching to
I
,
J
, or
K
.
