1.6 Warning about misuse
In case of inadequate or improper use or manipulations of
the component, personal hazards or damage to machinery or
plant components cannot be excluded. The relevant require-
ments of the standards EN 1088 and EN ISO 13850 must be
observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this operating instructions
manual. The manufacturer shall accept no liability for damages result-
ing from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary re-
pairs, conversions and modifications to the device are strictly forbidden;
the manufacturer shall accept no liability for damages resulting from
such invasive work, arbitrary repairs, conversions and/or modifications
to the device.

• Possibility to connect up to 4 sensors per interface,
e.g. safety magnetic switches of the BNS type, emergency
stop control devices, interlocking devices, etc.
• Current and voltage limitation of the input circuits
• Cross-wire monitoring of the input circuits
• Signalling output for each sensor (monitoring of both
circuits of the sensors)
• Green LED indications for UB and every sensor contact
• Cascading possible for the connection of up to 80 sensors
This device is designed as input expander module. The
safety function is only realised in conjunction with the
downstream basic device (SRB). To this effect, the device
must be connected in accordance with the wiring example!
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefore
the compliance with the Machinery Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The input expander modules for integration in safety circuits are
designed for fitting in control cabinets. They are used for the evaluation
of the signals of 1...4 sensors and the summarised transmission of the
signals to a downstream safety-monitoring module.
The function is defined as the opening of the enabling contacts 13-14
and 23-24 when one or more of the 8 sensor inputs are actuated. The
enabling paths with the outputs contacts 13-14 and 23-24 meet the
following requirements under observation of a PFH value assessment
and in conjunction with an SRB (control category 4 / PLe) (also refer to
chapter 2.5 "Safety classification"):
– Control category 3 – PL d to EN ISO 13849-1
(when multiple safety guards are opened within one work cycle)
– SIL 2 to IEC 61508
– SILCL 2 to EN 62061

(english)
The above-described requirements cannot be met by the
input expander module solely, but only in combination with
a safety-monitoring module as described in this manual.
To determine the Performance Level (PL) to EN ISO 13849-1 of the
entire safety function (e.g. sensor, logic, actuator), an assessment of all
relevant components is required.
