Electrical installation
Installation
The signal terminal block is equipped with the following signal terminals:
All binary inputs are enabled with an input voltage in the range of +8 V to 30 V. This
means they are +24 V compatible.
• NOTICE Possible damage to property.
Applying voltages of more than 30 V to the control terminals can damage the control-
ler.
– The voltage present on the control terminals must not exceed 30 V.
• INFORMATION
Terminals 7 and 9, see section "Overview of signal terminals" (page 26) can be used
as GND setpoint if MOVITRAC
®
LTE-B is controlled via PLC.
Termi-
