English
General data
Number of inputs max.
128
Number of outputs max.
16
Number of expansion modules max.
14
Number of expansion modules of the same type max.

Rated voltage
24 VDC  20 %/supply class II (LVLE)
Overvoltage category
II
Digital INPUTS
PNP active high (EN 61131-2)
OSSD (MSC-CB, FI8FO2, AC-FO2, AC-FO4)
PNP active high – 400 mA @ 24 VDC max. (per OSSD)
Digital OUTPUTS
PNP active high – 100mA @ 24 VDC max.
Response time (ms)
This response time is dependent on the following pa-
rameters:
1) Number of expansion 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.
