KL5151, KS5151, KL5152, KS5152 | 1-, 2-channel incremental encoder interface

The KL5151/KL5152 Bus Terminal is an interface with 24 V inputs for the direct connection of incremental encoders. A 32 bit (KL5151) or 16 bit (KL5152) counter with a quadrature decoder and a 32 bit (KL5151) or 16 bit (KL5152) latch for the zero pulse can be read, set or enabled. The KL5151 inputs can optionally be used as single or two-counter inputs. The KL5152 indicates the logical state of the signals via LEDs. The signal inputs use 0 V as the reference potential and are electrically isolated from the K-bus.
