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.26 shows how to connect an Art.506N relay.
