7.1.9.2 Relay Connection
Relays are located inside R1A and R1B (Relay 1) and
inside R2A and R2B (Relay 2) connectors. Relays do
not have polarity and therefore both terminals A or
B of the same relay can be used, for alternating or
continuous current voltages.
TERMINAL DESCRIPTION
R1A Relay 1 terminal A
R1B Relay 1 terminal B
R2A Relay 2 terminal A
R2B Relay 2 terminal B
Tab. 06
h Relays can be used for low working
voltages only (up to 30 Vac or 60 Vdc) and
with a maximum current of 2A. Use cables
with a section suitable for the load to be
controlled. The terminal can house cables
with a section comprised between 0.5 and
1.5mm
2 (AWG 30-16).
For further details on configuring and using the
relays, refer to "9.6.6.1 Alarms menu", page 37, page 38.
