Customer terminal block -X55 Siemens

Обзор



Customer terminal block -X55 represents the interface to the I/O devices and marshals a range of cabinet-internal signals to a central terminal block module mounted in the lower part of the cabinet.

It can be used for Motor Modules in the chassis format as well as together with options K90 (CU320-2 DP Control Unit) or K95 (CU320-2 PN Control Unit) for Basic Line Modules, Smart Line Modules, Active Line Modules and Booksize Cabinet Kits.

Дизайн



To connect signal cables on the customer side, terminal block -X55 includes terminals -X122, -X132, -X41 and -X46 (terminals -X1 to -X4 are used inside the cabinet and are not available). As a consequence, depending on the version (with/without option K90 or K95) the following digital inputs/outputs and/or signals are available:
