24V-NPN/PNP single-ended, supports real-time speed reporting of two encoder channels
Solidot · Pulse Counter Module
XB6S-PL20
The new generation of slice incremental encoder counting modules, using the X-bus backplane bus, can externally connect two 24V single-ended incremental encoders. The module supports functions such as Z-phase clearing, comparison output, and probe latching. Paired with our company's XB6S series couplers, it can be widely used in various industrial system equipment.
