4 Failsafe Relay
The failsafe relay is a digital output contact that can be used to communicate an alarm to another system
(e.g. remote terminal unit) if the server stops working. The failsafe relay is in open state (normally open)
when the server is powered down, and it is latched by the system when the server is powered up. An open
state will indicate that the server has no power or that something is wrong with the software running in the
server.
