8 MICRA SATEL
– analog [only in communication device mode] – to handle analog signals from devices
used in automation (measurement of temperature, pressure, rotation, etc.).
The devices to be connected to the zones can be supplied directly from the module (AUX
output) or from an additional power supply unit. The choice of the power supply source
should be made conditional upon the previous estimation of current consumption.

is to be connected in the same way).
3.6 CONNECTING SIREN
Relay outputs should be used to control a siren. The way in which the siren will be power
supplied should depend on an assessment of current consumption, which should be made
beforehand. The siren can be powered from the module AUX output, if the current
consumption by the siren does not exceed the output rating.
