Internal I/Os of the CIPer Model 50

Universal Inputs
The WEB-EAGLENX26XX is equipped with ten universal
inputs (UIs) configurable (in WEBs N4).
For information on the accuracy of the sensor inputs, their
differential measurement error, the characteristics (i.e., re-
sistances and resultant voltages in dependence upon tem-
perature) of the various different sensor types which can be
connected to them, and on the thresholds at which sensor
failures are recognized, see section "Appendix 2" on pg. 48.

Slow Binary Input Specifications
When configured as slow binary inputs, the universal inputs
of the CIPer Model 50 have the following specifications:
open contact ≥ 100 kΩ
closed contact ≤ 100 Ω
The polarity (normal = N.O. contact or reverse = N.C. con-
tact) configuration defines if a logical 1 or a logical 0 is
detected for a closed contact. This is done by selecting (in
WEBs N4) one of the following options:
closed external contact → state=1
normal (default)
open external contact → state=0
closed external contact → state=0
reverse
open external contact → state=1
Pulse Counter Specifications
Using WEBs N4, the universal inputs of the CIPer Model 50
can be configured as pulse counters (totalizers).
If the duty cycle is 50% / 50%, the pulse counter supports
up to 0.4 Hz. Counting is done on the rising edge.
