16 8540705 • 18/12/2012 • Rev.6CHARACTERISTICS OF OUTPUT RELAYSThe modules use two guided contacts safety relays (pin 5-6 and 7-8 of CJ6 onMJB1 and MJB2), (pin 5-6, 7-8 and 9-10 of CJ6 on MJB3 and MJB4), for the outputcircuit.These relays are specified by the manufacturer for voltages and currents greaterthan what is indicated in the technical data; nevertheless to guarantee correctinsulation and avoid damage or premature aging, protect each output line with a3.15 A delayed fuse and verify that the features of the load conform to theindications on the following table.MJB1/MJB2 MJB3/MJB4Number of contacts 2 N.A. 2N.A. - 1N.C.*Relay category (according to EN60947-5-1) AC15 / DC13Max commutable voltage 250Vac, 24VdcMin commutable voltage 10Vac/10VdcMax commutable current 2AMin commutable current 10mA@24VdcNumber of commutations (life) > 50 x 103 (el) / > 40 x 106 (mech)* 1N.C. = DO NOT USE AS A SAFETY CONTACTSAFETY DATAFEEDBACK CONNECTION ACTIVE FEEDBACK CONNECTION MISSINGPFHd SFF MTTFd DCavg PFHd SFF MTTFd DCavg8,16E-09 99,5% 71,02 99,0% tcycle1AC15(6A)4,60E-07 0,50 71,01738 0 tcycle1AC15(6A)6,78E-10 99,5% 851,50 98,9% tcycle2 4,43E-09 0,52 851,5035 0 tcycle24,35E-11 99,2% 13442,07 97,6% tcycle3 9,73E-11 0,69 13442,07 0 tcycle31,52E-09 99,5% 378,64 99,0% tcycle1 AC15(2A)1,86E-08 0,51 378,6359 0 tcycle1 AC15(2A)1,28E-10 99,4% 4523,66 98,5% tcycle2 3,62E-10 0,58 4523,66 0 tcycle29,14E-12 99,0% 67522,13 91,9% tcycle3 1,74E-11 0,87 67522,13 0 tcycle3tcycle1: 300s (one commutation every 5 minutes)tcycle2: 3600s (one commutation every hour)tcycle3: one commutation every day(PFHd according to IEC61508, MTTFd and DCavg according to ISO13849-1)
