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) the following digital inputs/outputs and/or signals are available: The customer terminal strip -X55 includes: | Motor Modules in chassis format | Line Modules |
