8.1.2. General data
Number of inputs max. 128
Number of outputs max. 16, dual-channel
Number of extension modules max. 14
Number of extension modules of the same type max. 4
Operating voltage 24 VDC ±20 % / class II supply (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 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.
