Relay - Setup
The type of relay (electronic switch) used in the Portable BLACKBOX are C Form . The relay break
the connection with one throw before making contact with the other (break-before-make). Meaning
that the change-over or double-throw contacts control two circuits namely: one normally-open
contact & one normally-closed contact with a common terminal. There are 3 types of change over


The disable state is the default & disables the relay.

With the Manual state you can set the "Normally Open Output" as either open / close. This
state enables the relay of the device to act as a switch - for example switching a fan on/off
should the temperature rise above/below a pre-configured condition.

In the Automatic state, this will set the relay's output as a function of
