2 Product overview
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).

Product overview
KM2002, KM2004, KM20088 Version: 3.2.0
Connection
Plug connectors are available for single and triple conductor connection methods.
Fig.3: Terminal module with plug connector for single conductor connection method (ZS2001-0002)
Fig.4: Terminal module with plug connector for triple-conductor connection method (ZS2001-0004)
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.

2.2 KM2002
2.2.1 Introduction
Fig.8: Digital Terminal Module with 16 output channels
Digital Terminal Module with 16 output channels (24VDC)
The terminal module KM2002 combines 16 digital outputs with 8 channels per plug connector in a compact
design with high packing density. The binary control signals are transferred (electrically isolated) to the
actuators at the process level. Like the standard Bus Terminals, the terminal modules are integrated in the
Beckhoff I/O system. Plug connectors with spring connections enable plug-in wiring and are available with 1
or 3 pins. LEDs integrated in the connector indicate the signal state for each channel directly at the wire. The
outputs are protected against overload and short circuit.
