2.1 Terminal Modules - System Overview
Fig.1: Bus Terminal Block
Better sensor and actuator functionality makes machines and systems more and more powerful. The Bus
Terminal reliably meets increased requirements for I/O signals through its modularity and compact design.
The existing Beckhoff Bus Terminal system is complemented by the new version of the EMxxxx / KMxxxx
Terminal Module with increased packing density. In many areas of application, cost benefits can be realized
through lower overall installed size and application-specific signal mix.
The new Terminal Modules are fully system-compatible. Like the Bus Terminals, they are bus-neutral and
can therefore be operated with any Beckhoff Bus Coupler and Bus Terminal Controller. Like the standard
Bus Terminals, the EM / KM modules are integrated in the I/O system and connected with the internal
terminal bus (E-bus / K-bus). Bus Terminals and terminal modules can be combined without restriction.
Plug connector
Like for the Bus Terminals, no tools are required for the wiring. Spring-loaded technology is used, however
the connection layer is pluggable (fixed wiring).

Connection
Plug connectors are available for single and triple conductor connection methods.

Product overview
KM10x2, KM10x4, KM10x810 Version: 3.2.0
Packing density
The Terminal Modules combine 16, 32 or 64 digital inputs or outputs on a very small area. This compact and
slimline design enables very high packing densities, leading to smaller control cabinets and terminal boxes.

Product overview

Digital terminal module with 16 input channels (24 VDC)
The terminal modules KM1002 and KM1012 combine 16 digital inputs with 8 channels per plug connector in
a compact design. The control signals are transmitted (electrically isolated) to the higher-level automation
device. Like the standard Bus Terminals, the terminal modules are integrated in the Beckhoff I/O system.
Plug connectors with spring connections enable permanent wiring and are optionally available with 1 or 3
pins. LEDs integrated in the connector indicate the signal state for each channel directly at the wire. The
KM1002 and KM1012 versions have input filters with different speeds.

EL66xx and EL67xx series can be snapped onto the following recommended mounting rails:
• DIN Rail TH35-7.5 with 1mm material thickness (according to EN60715)
• DIN Rail TH35-15 with 1,5mm material thickness
Pay attention to the material thickness of the DIN Rail

A maximum of 64 Bus Terminals or Bus Terminal Modules may be aligned to a Bus Coupler! An overall

Bus Terminal Modules does not overstrain the K-Bus power supply of the Bus Coupler!

Mounting and wiring
KM10x2, KM10x4, KM10x820 Version: 3.2.0
3.3 Mounting and demounting - terminals with traction
lever unlocking
The terminal modules are fastened to the assembly surface with the aid of a 35 mm mounting rail (e.g.
mounting rail TH 35-15).
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the recommended mounting rails under the terminals and cou-
plers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the Bus Terminals!
Mounting
• Fit the mounting rail to the planned assembly location.
and press (1) the terminal module against the mounting rail until it latches in place on the mounting
rail (2).
• Attach the cables.
Demounting
• Remove all the cables. Thanks to the KM/EM connector, it is not necessary to remove all the cables
separately for this, but for each KM/EM connector simply undo 2 screws so that you can pull them off
(fixed wiring)!
• Lever the unlatching hook on the left-hand side of the terminal module upwards with a screwdriver (3).
As you do this
◦ an internal mechanism pulls the two latching lugs (3a) from the top hat rail back into the terminal
module,
◦ the unlatching hook moves forwards (3b) and engages
