BECKHOFF KL1154 - Manual

The KL1154 and KL1164 digital input terminals acquire the binary control signals from the process level and transmit them, in an electri-
cally isolated form, to the higher-level automation unit. The KL1154 and KL1164 versions have input fi lters of different speeds. Sensors that
switch to the positive potential or to 0 V (ground) can be connected to the KL1154 and KL1164 versions. The Bus Terminals contain four
channels that indicate their signal state by means of light emitting diodes.
