Beckhoff KL2 Series User Manual

Product overview
KL2xxx and KS2xxx 19Version: 3.0.0
4-channel, digital output terminal, 24V
DC
The KL2404 and KL2424 digital output terminals connect the binary 24V control signals electrically isolated
with the actuators. The Bus Terminals each contain four channels, whose signal states are displayed by
LEDs. The variants KL2404 and KL2424 have different maximum output currents. The 4-channel Bus
Terminals enable the direct connection of four 2-wire sensors. Four ground connection points are provided.
