NOTICE!
Risk of damaging the PLC module!
The following things have to be considered when connecting input and output
voltages to the module:
–
All 230 VAC feeds must be single phase from the same supply system.
–
Connection of 2 or more relay contacts in series is possible; however, vol-
tages above 230 VAC and 3-phase loads are not allowed.
–
The 4 switch-over contacts of the relays are electrically isolated from
channel to channel. This allows to connect loads of 24 VDC and 230 VAC to
relay outputs of the same module. In such cases it is necessary that both
supply voltages are grounded to prevent unsafe floating grounds.
–
All input signals must come from the same phase of the same supply
system (together with the used neutral conductor). The module is designed
for 120/230 VAC max., not for 400 VAC, not even between two input termi-
nals.
–
All neutral conductor connections must be common to the same supply
system, since the terminals 4.0 to 4.3 are interconnected within the module.
Otherwise, accidental energization could occur.
NOTICE!
Risk of damaging the PLC module!
There is no internal short-circuit or overload protection for the relay outputs.
Protect the relay contacts by back-up fuses of 6 A max. (characteristic gG/gL).
Depending on the application, fuses can be used for single channels or module-
wise.
The module provides several diagnosis functions (see chapter Diagnosis and State LEDs

I/O Configuration
The module itself does not store configuration data. It receives its parameterization data from
the master device of the I/O bus (CPU or bus module) during power-up of the system.
Hence, replacing I/O modules is possible without any re-parameterization via software.
If the external power supply voltage via UP/ZP terminals fails, the I/O module
loses its configuration data. The whole station has to be switched off and on
again to re-configure the module.
