Digital INPUTS
PNP active high (EN 61131-2)
OSSD (MSC-CB, FI8FO2, AC-FO2, AC-FO4)
PNP active high – 400 mA at 24 VDC max. (per OSSD)
Digital OUTPUTS
PNP active high – 100 mA at 24 VDC max.
Response time (ms)
This response time is dependent on the following parameters:
1) Number of extension modules installed
2) Number of operators
3) Number of OSSD outputs
The correct response time is calculated by the software EUCHNER Safety Designer
(see project report).
Fault reaction time (ms)
The fault reaction time corresponds to the reaction time, except on SPM modules
with an encoder/proximity switch interface.
In this case the fault reaction time is 2 s.
