6.1.2 Electronics base

The electronics base holds the entire electronics for an Inline terminal and the potential

and data routing.

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 6-1).

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.

Snap-on mecha-

nism/latching

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 Sec-

tion “Basic information about mounting” on page 105).

Keyway/featherkey con-

nection

The featherkeys are on the left-hand side of the terminal (Figure 6-1). 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.

Base colors The base and the appropriate connectors for the different voltage areas are of different

colors (see Section “Electronics base and connectors for the different voltage areas” on

page 20).

6.1.3 Connectors for terminals in the 24 V DC and

120 V AC/230 V AC areas

The I/O or supply voltages are connected using a pluggable connector. For more detailed

information about the Inline connectors, please refer to Section 7, “Inline connectors”.
