KeConnect - I/O modules


Flexible configurability

The MM 240/A is an incremental encoder module of the KeConnect C2 product line. This module is attached directly to a CPU module or can be operated with all KEBA controls by means of a bus coupler. The module is equipped with standardized connectivity for two path-measurement systems.

The positioning module can be used for precision measurement of position or speed with a wide variety of sensors. Encoder inputs have direct 5V or 24V supply for the encoders, and standard plugs make wiring easy.

  • Path measurement: Forward/backward counter of increments by means of tracks A and B
  • Single, double, quadruple evaluation
  • 32-bit resolution
  • Speed measurement through sampling with internal time basis
  • Rotary encoder monitoring via zero track information
  • Latch function of the counter status via a 24 V external latch input (sink and source)
  • Latch function of the counter status via zero pulse
  • Sensor break monitoring of tracks A, B and zero


The C2 positioning modules are used for connecting a wide range of encoders. Thanks to the flexible configurability of encoders from a variety of manufacturers, they can be adapted to individual requirements.


The sensors are connected to the positioning modules via standard plug connections. With the internal encoder supply of 24V or 5V, cabling work is reduced to a minimum.

Speed output

In addition to the high resolution of the incremental encoders for the counter value, the speed value is also output with very high accuracy. Through the direct availability of the speed value in the application, complex calculations can be avoided.
