BECKHOFF KL1104 User Manual

Datasheet for KL1104, KL1114, Version 1.3

Four channel, digital input terminals, 24 VDC

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. The KL1104 and KL1114 are particularly useful for space-saving use in control cabinets.

ATEX - Special conditions

Observe the special conditions for the intended use of
Beckhoff fieldbus components in potentially explosive areas (directive 94/9/EU)!

WARNING

• The certified components are to be installed in a suitable housing that guarantees a
protection class of at least IP54 in accordance with EN 60529! The environmental
conditions during use are thereby to be taken into account!

• If the temperatures during rated operation are higher than 70°C at the feed-in points of
cables, lines or pipes, or higher than 80°C at the wire branching points, then cables must
be selected whose temperature data correspond to the actual measured temperature
values!

• Observe the permissible ambient temperature range of 0 - 55°C for the use of Beckhoff
fieldbus components in potentially explosive areas!

• Measures must be taken to protect against the rated operating voltage being exceeded by
more than 40% due to short-term interference voltages!

• The individual terminals may only be unplugged or removed from the Bus Terminal system
if the supply voltage has been switched off or if a non-explosive atmosphere is ensured!

• The connections of the certified components may only be connected or disconnected if the
supply voltage has been switched off or if a non-explosive atmosphere is ensured!

• The fuses of the KL92xx power feed terminals may only be exchanged if the supply voltage
has been switched off or if a non-explosive atmosphere is ensured!

• Address selectors and ID switches may only be adjusted if the supply voltage has been
switched off or if a non-explosive atmosphere is ensured!
