Terminals on the
PLA-H 08-04-04
The interfaces of the PLA-H 08-04-04 module are electrically separated
from the 230 V line power in accordance with EN 50178.
Sensors and external devices that are connected to the PLA-H 08-04-04
module must be supplied exclusively either with 24 V NC or with 24 V PLC.
The inputs and outputs of the module are not galvanically isolated internally.
In the HSCI system, the two supply voltages must not be connected with
each other, however.
Sensors and external devices that are connected to the PLA-H 08-04-04
module and are supplied with 24 V NC must have double basic insulation.
