Safety Data - Reer JANUS MJBOX Manual Del Usuario

CHARACTERISTICS OF OUTPUT RELAYS
The modules use two guided contacts safety relays (pin 5-6 and 7-8 of CJ6 on
MJB1 and MJB2), (pin 5-6, 7-8 and 9-10 of CJ6 on MJB3 and MJB4), for the output
circuit.
These relays are specified by the manufacturer for voltages and currents greater
than what is indicated in the technical data; nevertheless to guarantee correct
insulation and avoid damage or premature aging, protect each output line with a
3.15 A delayed fuse and verify that the features of the load conform to the
indications on the following table.
