A
List of Terminals
EDGE Main Controller
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
Automation - 24V Communication bus 1 - power supply 24VDC
Automation - A
Communication bus 1 - Signal A of RS485 communication
Automation - B Communication bus 1 - Signal B of RS485 communication
Automation - GND Communication bus 1 - power supply return

Safety - GND Communication bus 2 - power supply return
3-Slot and 6-Slot Expansion Box
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.
