KL9400 EtherCAT Terminal

The Beckhoff KL9400 is a K-bus power supply terminal used to refresh the K-bus current in a Bus Terminal configuration. When a large number of terminals are connected, the standard Bus Coupler's power supply (1.75 A for standard couplers) may be insufficient; the KL9400 feeds an additional 2 A into the K-bus to ensure stable data exchange.
