Beckhoff KL1 Series User Manual

Product overview
KL1xxx26 Version: 1.0.0
Eight-channel, digital input terminals, 24 V
DC
The digital input terminals KL1408 and KL1418 (positive switching) and KL1488 and KL1498 (negative
switching) acquire the binary control signals from the process level and transmit them, in an electrically
isolated form, to the higher-level automation unit. The Bus Terminals each contain eight channels, whose
signal states are displayed by LEDs. They are particularly suitable for space-saving use in control cabinets.
By using the single-conductor connection technique a multi-channel sensor can be connected in the smallest
space with a minimum amount of wiring. The power contacts are looped through. For the KL1408 and
KL1418 Bus Terminals, the reference ground for all inputs is the 0V power contact. For the KL1488 and
KL1498 Bus Terminals, the reference point for all inputs is the 24V power contact. These versions have
input filters with different speeds.
