Compact modules K45

The K45 series of compact modules supplements the large K60 compact modules, which have a proven track record in industry. They are the logical consequence for rounding off the bottom end of the existing product range.

The acclaimed advantages of the existing K60 compact modules are fully emulated by the K45 modules. The K45 modules have a substantially smaller basic area and installation depth, however.

Yet in spite of these small dimensions all the modules have large labels and an integrated addressing socket.

Two mounting plates are offered for the K45 compact modules:

• Mounting plate for wall mounting
  This has a hole pattern that is identical to that of the K60 compact modules. This means that K60 compact modules can be mounted together with K45 modules in an aligned arrangement. The shaped cables can be inserted in the recesses of the mounting plates, where they cause no hindrance.
• Mounting plate for standard rail mounting

Connection of the AS‑Interface shaped cables

The mounting plate and the compact module are joined together by means of a screw, with simultaneous contacting of the AS‑Interface cable by the service-proven insulation piercing method.

Now, mounting the AS‑Interface shaped cables is in fact easier than ever. The yellow and black AS‑Interface shaped cable can be inserted into the mounting plates from the left or right regardless of the position of the coding lug. The correct polarity of the applied voltages is guaranteed.

Addressing and connection of sensors/actuators

Addressing of the K45 compact modules is performed using an addressing socket integrated in the module. The addresses can also be assigned after the module is installed.

K45 modules with a maximum of four digital inputs and outputs

These compact modules contain up to four or M8 or M12 standard connections for inputs and outputs. Using M12 or M8 standard connectors, a maximum of four sensors and four actuators can be connected to the compact module. Depending on the module, the sockets can be assigned in duplicate.

Pin assignment: Y - i.e. two sensors or one sensor/actuator are connected via one socket.

K45 modules with a maximum of eight digital inputs

These modules have eight digital inputs for connection through M12 plugs. The sockets have duplicate assignments.

Pin assignment: Y - i.e. two sensors or one sensor/actuator are connected via one socket.

The module requires two AS‑Interface addresses for processing all eight inputs. Addresses can be assigned using a double addressing socket integrated in the module.

K45 modules in compliance with AS‑i Specification V3.0 with four digital inputs and outputs/four digital outputs

The extended address mode (A/B addresses) according to AS‑Interface Specification V3.0 enables connection of up to 62 slaves on one AS‑i network. With this extended address mode, four outputs are now possible even with A/B slaves (instead of only three outputs possible up to now with Specification V2.1). Hence with full expansion of an AS‑Interface network, there are now 248 inputs as well as 248 outputs available on one AS‑Interface system.

Points to bear in mind:

• These modules can be used only with a master according to AS‑i Specification V3.0.
• The cycle times for the outputs may be up to 20В ms.

Depending on the module, the sockets can be assigned in duplicate.

Pin assignment: Y - i.e. two sensors or one sensor/actuator are connected via one socket.
