XB6S-PL20 - Pulse counter module - Solidot Technology


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.
