KEBA KeConnect MM 240/A Positioning module

Product features

• 2 incremental encoder inputs

with 12- or 32-bit resolution

• 2 latch inputs as sink or source input

• Electronic parameter chip

Short description

The MM 240/A is an incremental encoder 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 bus couplers.

MM 240/A features

• Position 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 an external latch input 24 V (sink and source)

• Latch function of the counter status via zero pulse

• Sensor failure monitoring of tracks A, B and zero
