2.5 Safety classification
Standards:
EN ISO 13849-1, IEC 61508
PL:
STOP 0: up to d
Category:
STOP 0: up to 3
DC:
STOP 0: > 60 % (low)
CCF:
> 65 points
PFH value:
STOP 0: 2.00 x 10
-7
/h
SIL:
STOP 0: up to 2
Service life:
20 years
The PFH value of 2.00 x 10
-7
/h applies to the combinations of contact
load (current through enabling contacts) and number of switching cy-
cles (n
op/y
) mentioned in the table below. At 365 operating days per year
and a 24-hours operation, this results in the below-mentioned switching
cycle times (t
cycle
) for the relay contacts.
Diverging applications upon request.

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.
3. Mounting
3.1 General mounting instructions
Mounting: snaps onto standard DIN rails to EN 60715.
Snap the bottom of the enclosure slightly tilted backwards in the DIN
rail and push down until it latches in position.
3.2 Dimensions
All measurements in mm.
Device dimensions (H/W/D): 126 × 48 × 61 mm
with plug-in terminals: 126 × 48 × 53 mm
4. Electrical connection
4.1 General information for electrical connection
As far as the electrical safety is concerned, the protection
against unintentional contact of the connected and therefore
electrically interconnected apparatus and the insulation of the
feed cables must be designed for the highest voltage, which
can occur in the device.
The electrical connection may only be carried out by authorised
personnel in a de-energised condition.

6. Set-up and maintenance
6.1 Functional testing
The function of the component must be tested. The following conditions
must be previously checked and met:
1. Correct fixing
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damage
4. Check the electrical function of the connected sensor technology and
their influence on the safety-monitoring module and the downstream
actuators
