Beckhoff KL9187 EtherCAT IO Terminal Module

Beckhoff KL9187 is a dedicated potential distribution terminal (eight-way) in the KL9xxx EtherCAT I/O family. It provides eight terminals, all tied to a single potential (0 V DC), enabling the tap-off of supply voltage or reference ground to multiple devices without needing extra bus bars or wiring. This compact module streamlines power distribution in Beckhoff EtherCAT installations by allowing the same 0 V potential to be shared across multiple inputs, sensors, or actuators without reconfiguring the bus. As a passive power-distribution accessory, KL9187 does not process signals itself; it simply distributes the designated potential alongside the other KL terminals in the system. The KL9187 is documented as eight 0 V DC distribution points, designed to support efficient harnessing of return rails across distributed automation layouts.
