E1.4
The installed I/O component group has one digital input port. The inputs E1.5 - E1.8)
are already partially wired internally and occupied by signal inputs and not usable by
the user. The digital inputs E1.1 - E1.4 may be assigned by the user.
Properties
- Optoelectronic coupler inputs
- Input current approx. 8mA
