List of Terminals
EDGE 2 Controllers
Terminal name Description
Alarm - COM Alarm relay input, the COM (Common) is the voltage source needed to switch
Alarm - NO (Normally
Opened) Alarm relay output, When a relay contact is normally open (NO), there is an opened con-
tact when the relay is not energized
Alarm - NC (Normally
Closed) Alarm relay output, When a relay contact is Normally Closed (NC), there is a closed con-
tact when the relay is not energized
Functional earth Functional Ground Terminal Primarily used for functional earth terminals which are gen-
erally associated with test and measurement circuits. These terminals are not for safety
earthing purposes but provide an earth reference point

Terminal name Description
IN (x) Analog inputs can set in 0-5V mode, in dry contact mode, in 4-20mA mode, in tempera-
ture mode. Inputs are used for sensors : temperature probes, humidity probes, static
pressure probes, water meters, dry contacts.
GND(x) close to IN(x) Analog inputs returns. Inputs are used for sensors : temperature probes, humidity
probes, static pressure probes, water meters, dry contacts.
24V+
24VDC Supply Outputs are used to supply sensors, maximum current per output : 50mA
GND close to 24V+ Returns of 24VDC supply outputs used to supply sensors
RELAY(x) – COM Relay inputs, the COM (Common) is the voltage source needed to switch.
RELAY (x) – NO Relay outputs, when a relay contact is normally open (NO), there is an open contact
when the relay is not energized.
RELAY(x) – NC Relay output, when a relay contact is Normally Closed (NC), there is a closed contact
when the relay is not energized.
