Analog Outputs
The WEB-EHSERIESNX26XX is equipped with four analog outputs (AOs).
In the event of an application stop (e.g., during application download), the analog outputs assume the safety
positions configured in WEBs N4.
The analog outputs can be configured in WEBs N4 as binary outputs (with an output of 0 V or 10 V, as the
case may be).

Binary Inputs / Pulse Counters
The WEB-EHSERIESNX26XX is equipped with four binary inputs (static dry-contact inputs) / pulse counters
(fast totalizers).

Binary Input Specifications
The binary inputs of the CIPer Model 50 are static dry-contact inputs. This reduces the wiring effort, as it is
then not necessary to distribute an auxiliary voltage signal.

(short-circuit current: 2.0 mA)
The polarity (normal = N.O. contact or reverse = N.C. contact) 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:
