4.1 General Service Conditions
This section describes the general requirements of installing, wiring and troubleshooting the Kuhnke
FIO modules.
For a list of System Properties of
Kuhnke FIO refer to chapter 0, page 457.
Subsequent chapters explain the specific properties of each of the modules.
4.2 Mechanical Design
The picture below shows the basic layout of the Kuhnke FIO modules.
The bus coupler and the I/O modules differ in their connectors and indicators, however.
The housing mount consists of an aluminium profile with an integral snap-on device used to snap the
module to a 35mm DIN rail. The housing trough including the optical fibres for the status indicators,
the side face and the front is made of plastic and contains the module. The optical fibres for the signal
state indicators (LEDs) are located next to the spring-assisted combi plug. They slightly protrude from
the housing and allow a clear diagnosis at a glance.
