Manual operating module with K-Bus interface

Manual operating modules with K-Bus interface

The manual operating modules have been developed for the switching, controlling and observation of digital and analog signals.
They enable the setting and reading of data and values in case of failure of a controller.

The manual operating modules provide the functionality of a local priority control/display unit according to EN ISO 16484-2:2004, Chapter 5.4.3.
The equipment manufacturer must ensure access protection against unauthorized operation by installing suitable components (see EN ISO 16484-2:2004, Chapter - Access protection for local priority control/display units).

For output modules manual operation can be disabled via the user program. See chapter Control and status byte of the modules KL8524, KL8528 and KL8548.

The manual operating modules can be installed in the control cabinet door using a snap-in technique; they are wired inside the control cabinet.
Up to 31 modules can be inserted via the K-bus interface with K-bus extension. This facilitates integration of the manual operating modules in the universal bus terminal system.

Connection to the KL9309 signal-independent transfer terminal takes place via ribbon cable. The signals are electrically isolated. Power and error LEDs indicate the status of the modules.

By means of installation in the control cabinet door, the modules can be operated without having to open the control cabinet door.

A total of five different modules are available:

  • KL8500 | Placeholder module
  • KL8519 | Signal module, 16 digital input channels
  • KL8524 | Output module, 4 x 2 digital output channels
  • KL8528 | Output module, 8 digital output channels
  • KL8548 | Output module, 8 analog output channels

TwinCAT Version

The manual operating modules are supported from TwinCAT 2.11 R3 (build 2221) or higher.

Older TwinCAT versions may also be able to support the manual operating modules, if a current bus terminal configuration file (TcTerminals) is used.

The current bus terminal configuration file is available from the Beckhoff website:
