PHOENIX CONTACT
5.1.2
The electronics base holds the entire electronics for an Inline terminal and the potential and
data routing.
Potential and data routing are located in the base. As all terminals are snapped onto the DIN
rail, the position of the interfaces between the terminals in relation to the DIN rail is the same
for all terminals. The advantage of this is that terminals of different sizes can be integrated
into the station.
The knife contacts are located on the left-hand side of the terminal (shown in Figure 5-1).
They snap into the featherkeys of the next terminal on the left when the station is mounted.
The type of routing contacts (i.e., potential or data) that are on each terminal depends on
the function of the terminal and is shown in the circuit diagram of the relevant
terminal-specific data sheet.
Pressing the front and back snap-on mechanism at the same time releases the latching,
enabling the terminal to be removed by pulling it straight back from the DIN rail (see "Basic
information about mounting" on page 9-2).
The featherkeys are on the left-hand side of the terminal (Figure 5-1). They snap into the
keyways of the next terminal on the left when the terminal is mounted on the DIN rail. The
featherkeys are also referred to as locking clips and the keyways as guideways.
The base and the appropriate connectors for the different voltage areas are of different
colors (see "Electronics base and connectors for the different voltage areas" on page 3-5).
5.1.3
The I/O or supply voltages are connected using a pluggable connector. For more detailed
information about the Inline connectors, please refer to Section 6, "Inline connectors".
