4 Wiring
Cables:
2/3 wire shielded cable
Proper section (minimum 0.5mm², maximum 2.5 mm²)
Compliant with local laws and regulations in force
All voltage free relay contact can only be connected to SELV circuits.
Refer to Figure 1 - RELAY, page 22.
The OUT output illustrated in the diagram is used as a power source and is programmed as continuously active.
The illustrated connection does not supervise the cable and does not signal connection faults.
EN54:
Refer to Figure 2 - RELAY - inv, page 22.
If you wish to configure a RELAY output as a fault signalling output, you must complete the
connections as shown in the wiring diagram opposite.
In compliance with the regulations in force, the output must be configured as "inverted" in
order to switch to fault condition when the system is completely without power.
Therefore, in stand-by status (no faults present on the system) terminals C and NC will be
closed, whereas terminals C and NO will be open.
5 J and E type relay output wiring (EN54)
Cables:
2-wire shielded cable
Proper section (minimum 0.5mm², maximum 2.5 mm²)
Compliant with local laws and regulations in force
EN54:
Refer to Figure 3 - RELAY - J, page 22.
To make a type J output (output for the activation of a remote fault-signalling device as
required by EN54-2, [A]), you must use a remote communication device which is compliant
with EN54-21 regulations [B] and which must have a normally-open supervised activation
input [C], a normally-closed fault signalling output [D] and a normally-open output to
provide feedback indicating successful communication [E].
This is done by making the connection illustrated in the figure, using a relay output (of an
IFM24160 module, IFM4R module or relay module) [A] configured as "communicator fault
condition output" and an input of an I/O module [F] configured as "communicator fault
condition input".
EN54:
Refer to Figure 4 - RELAY - E, page 23.
To construct a type E output (output for the activation of a remote alarm-signalling device
as required by EN54-2, [A]), you must use a remote communication device which is
compliant with EN54-21 regulations [B] and which has a normally-open supervised
activation input [C], a normally-closed fault signalling output [D] and a normally-open
output to provide feedback indicating the successful communication [E].
This is done by making the connection illustrated in the figure, using a relay output (of an
IFM24160 module, IFM4R module or relay module) [A]configured as "communicator alarm
condition output" and an input of an I/O module [F] configured as "communicator fault
condition input".
