I/O Modules
Pluggable I/O Modules
There are 2 variants of pluggable I/O modules:
Panel Bus I/O modules with communication via Panel
Bus (light-gray housings). Panel Bus I/O modules are
automatically commissioned (with firmware download) by
the XCL8010 Controller.

(FTT10-A, link power

controllers.
Mixed I/O Modules
Besides the
pluggable
Panel Bus I/O modules (consisting of
a terminal socket and a removable electronic module), there
are also
mixed
Panel Bus I/O modules. Specifically: the
XF830A and XFU830A are mixed Panel Bus I/O modules,
featuring an integrated terminal socket and a variety of
inputs and outputs.
Mixed Panel Bus I/O modules have a light-gray housing and
are likewise automatically commissioned (with firmware
download) by the XCL8010 Controller.
Terminal Sockets
Pluggable I/O modules must be mounted on the appropriate
terminal sockets. Pluggable Panel Bus I/O modules and

Bus I/O modules use the same
terminal sockets. These terminal sockets are available with
push-in terminals (XS82…) or with screw-type terminals
(XSU82…).
Mixed I/O modules feature an integrated terminal socket.
Color Coding
To distinguish modules and components, the following color
coding is used:
Color

Red
All of the user-accessible adjustable
mechanical parts (i.e., bridge connectors
and locking mechanism) and operating
controls (manual overrides, etc.)
