Beckhoff KL1 Series User Manual

Product overview
KL1xxx14 Version: 1.0.0
Four-channel, digital input terminals, 24V
DC
The KL1104 and KL1114 digital input terminals acquire the binary control signals from the process level and
transmit them, in an electrically isolated form, to the higher-level automation unit. The KL1104 and KL1114
versions have input filters of different speeds. The Bus Terminals contain four channels that indicate their
signal state by means of light emitting diodes.
