Digital INPUTS
PNP active high (EN 61131-2)
OSSD (CMM, C 8I 2O, C 2OSSD, C 4OSSD)
PNP active high - 400mA@24VDC max (each OSSD)
Digital OUTPUTS
PNP active high - 100mA@24VDC max
Response time (ms)
This response times depends on the
following parameters:
1) Number of Slave modules installed
2) Number of Operators
3) Number of OSSD outputs
Failure Response time (ms)
This parameter corresponds to the response
time, with the exception of C ES modules
with Encoder/Proximity inerface where is 2s.
