6.1.4.3 Relay connection
The relay can be used for low working
voltages only (up to 30Vac or 60Vdc) and
with a maximum current of 1A. Use cables
with a section suitable for the load to be
controlled and use cables with a minimum
section of 0.25mm² (AWG 24) and maximum
section of 1.5mm² (AWG 16).
The R1A and R1B relay clamps are located in the J4
connector. The relay does not have polarity making it,
therefore, irrelevant to use clamp A or B of the same
relay for AC or DC voltages.
