Function description
The PSS67 device PSS67 IO1 16FDI consists of a head module of the performance class
PSS 4000 I/O with a SafetyNET p interface and four input modules. The head module and
input modules are connected via an internal module bus. The inputs of each module are im-
plemented on two plug-in connectors. Plug-in connectors X01 and X02 are used for the
module on slot 0.

Supply voltages
}
Device supply
Supply voltage for the device, sensors and test pulses. The device supply is fed in at
the plug-in connector X31 and is forwarded to the plug-in connector X32. By forwarding
in this way, additional devices can be supplied. The module supply for supplying the
device and the periphery supply for supplying the sensors and test pulses is generated
internally from the device supply.

Load supply
Supply voltage for the actuators. The supply voltage for load supply is not required for
the operation of this device. The load supply is fed in at the plug-in connector X31 and
is forwarded to the plug-in connector X32.
Device supply and load supply are galvanically isolated within the device.
