Connectors
The connection of the I/O or supply voltages is made by using a connector
that can be plugged on or off the modules.
Connector Types
The following connector types are available:
(1) Standard connector (IC220TBK082, 085, 087)
The standard connector is used for the connection of two signals in 4-wire
format (e.g., digital input/output signals). The standard connector housing is
also used for power and segment terminals and relay terminals, although
the types are NOT interchangeable.
(2 )Shield connector (IC220TBK061)
This connector is used for signals connected using shielded cables (e.g.,
analog I/O signals, high-speed counter inputs, network cable). The FE or
shielding is connected by a shield clamp.
(3) Extended, connector (IC220TBK122, TBK123)
This connector is used for the connection of four signals in 3-wire format
(e.g., digital input/output signals).
Regardless of the width of the electronics base, the connectors are provided
with a standard width. Wider modules may require multiple connectors.
Connector Identification
Connectors have terminal points that are color coded corresponding to their
functions:
