Data sheet for KL2702, Version 2.0
2-channel solid state load relay up to 230 VAC/DC
The KL2702 output terminal uses an electronic load relay to switch a mains voltage of up to 230 VAC/DC. The
switching element is a high-power MOSFET, which is connected to the power contact potential. As a
semiconductor switch, it is not subject to wear. The KL2702 terminal has two independent outputs. Its signal
state is indicated by means of light emitting diodes.

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