Relay output To use the relay outputs in a wet
location, observe the following
DANGER safety instruction.
• Normally open or normally closed,
depending on the wiring
• max. 30VAC and 42Vpeak/ 2A
or 60VDC/ 1A max.
Alarme

• Error signal • 22mA and 0Hz
DANGER
Danger due to the operation of the relay outputs of a UL
device in a wet location.
▶ If a UL device is used in a wet location:
- energize the relay outputs with an alternating voltage of
max. 16Vrms and 22.6Vpeak.
- or energize the relay outputs with a direct voltage of
max.35VDC.
