Characteristics of the output circuit.
For the output circuit, the safety relay uses two guided contact safety relays.
These relays are rated by the manufacturer for voltage and current values above those
indicated in the technical data; however, to assure correct insulation and to avoid
damage or premature aging, protect each output line with a 3,15A slow-blow fuse and
check that load characteristics comply with the indications given in the table below.
Minimum switching voltage 18 Vdc
Minimum switching current 20 mA
Maximum switching voltage 250Vac
Maximum switching current 2A
Warnings regarding the connection cables.
• For light curtain/safety interface connections of more than 50m, cables
with a cross-section of at least 1mm
2
must be used.
• It is good practice to separate the power supply of the safety relay from that of
other electrical equipment (electrical motors, inverters, frequency variators) or
other sources of disturbance.
• The path of the connection cables between the safety relay and the
sensors, the connection referring to the feedback contact must be different
from that of other power cables.
