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.
Product overview 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.
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.

Mounting and wiring 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.
