CONNECTING A SECONDARY DEVICE TO THE AUXILIARY OUTPUT (AO)
Since the auxiliary output
AO
is a transistor switched output (switched low output) it can be connected to a relay (e.g. an Art.506N).
This is particularly useful if a secondary device requires triggering.
Fig.13
shows how to connect an Art.506N relay.
