4-10 safety relays monitoring safety relays minotaur MSR5T description the MSR5T has 1 n.c. single channel input for use with gate interlocks and emergency stop buttons in lower risk applications. the MSR5T has output monitoring that can accommodate an automatic/manual reset function. automatic/manual reset can use a jumper or can be used to check operation of the contacts. the MSR5T has 3 n.o. safety outputs and 1 n.c. auxiliary output. the safety outputs have independent and redundant internal contacts to help ensure the safety function. the auxiliary contact is a nonsafety output intended to provide an external signal about the status of the safety outputs. the minotaur power supply converts either 110v ac or 230v ac to 24v dc. it is intended to be used with an MSR5T or a ferrotek noncontact interlock. when used with the MSR5T, the minotaur power supply acts like a 110v ac (230v ac) input module allowing a single channel 110v ac (230v ac) circuit to be wired directly into a safety circuit. features ? category 4 per en 954-1 ? stop category 0 ? single channel input ? 3 n.o. safety outputs ? 1 n.c. auxiliary output ? 22.5mm wide housing ? optional 110/230v ac input module applications -- + contactor monitoring circuit contactor switching circuit supply inclusive of switching circuit contactor monitored by minotaur s witc h ing circuit s upp l y MSR5T specifications ? see output ratings on page 1-29 for details. consult factory for ratings not shown. standards en 954-1, iso13849-1, iec/en 60204-1, iec 60947-5-1, ansi b11.19, as4024.1 category cat. 4 per en 954-1 approvals c-tick, ce marked for all applicable directives, culus and tuv power supply 24v ac/dc15% 50/60hz power consumption <4va safety inputs 1 n.c. maximum input resistance 200 ? reset automatic/manual outputs 3 n.o. safety; 1 n.c. auxiliary ? output utilization per iec 60947-5-1 (inductive) b300 ac-15 4a/250v ac, 4a/120v ac p300 dc-13 3a/24v dc thermal current (non switching) 4a fuses, output 5a quick acting min. switched current/voltage 10ma/10v maximum dropout time 90ms indication leds green = output impulse withstand voltage 2500v installation group c in accordance with vde 0110 pollution degree 3 operating temperature -10c to +55c (+14f to +131f) humidity 90% rh enclosure protection ip40, (nema 1), din 0470 terminal protection ip20, din 0470 conductor size 1 x 2.5mm 2 (14awg) stranded, 1 x 4mm 2 (12awg) solid torque settings?terminal screws 1n ? m (8.85lb ? in) case material red polycarbonate mounting 35mm din rail weight 210g (0.46lbs) electrical life 220v ac/4a/880va cos ? =0.35 220v ac/1.7a/375va cos ? = 0.6 30v dc/2a/60w 10v dc/0.01a/0.1w 100,000 operations 500,000 operations 1,000,000 operations 2,000,000 operations mechanical life 2,000,000 operations vibration 0.75mm (0.30in) peak, 10-55hz shock 30g, 11ms half sine the MSR5T monitors itself for any internal fault contactors: provides contactor monitoring if two or more contactors are used the safety function is ensured by the minotaur
