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 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. Therefore, the manual operating modules can be integrated 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.
