Relays are programmable switches that can be used to perform many different functions.
They can be used to turn lights on and off, control sounders, or for status indications. In this

(START), and when to deactivate (STOP). Each of these is described below.
The control supports a total of 4 output relays.
The 4204 Relay modules provide Form C (normally open and normally closed) contacts.
