4-24 safety relays monitoring safety relays minotaur MSR23M description the MSR23M control unit is designed to monitor 4 wire safety mats that are connected together to form a safeguarded zone. the size of the safeguarded zone is limited by the total input impedance (100 ohms maximum) created by the wiring and connections. the controller is designed to interfa ce with the control circuit of the machine and includes two safety relays to ensure control redundancy. the controller detects a presence on the mat, a short circuit, or an open circuit. under each of these conditions, the safety output relays turn off. when interfaced properly, the machine or hazardous motion receives a stop signal, and an auxiliary output turns on. features ? category 4 ? stop category 0 ? removable terminals ? monitored or automatic reset ? 4-wire safety mats sensing ? third party approval?bg specifications ? see output ratings on page 1-29 for details. consult factory for ratings not shown. standards en 954-1, iso 13849-1, iec en 60204-1, iec 60947-5-1, ansi b11.19, as 4024.5 category cat. 4 per en 954-1 (iso 13849-1) approvals ce marked for all applicable directives, bg and csa (24v only) power supply 24v ac/dc or 110v ac power consumption 2w inputs 2 n.c., 4-wire safety mat maximum input resistance 100 ohms reset monitored man. or auto./man. outputs 2 n. o. safety; 1 n.c. auxiliary ? output utilization per n.o. iec 60947-5-1 (inductive) n.c. b300 ac-15; 3a/250v ac, 3a/125v ac p300 dc-13; 2.5a/24v dc b300 ac-15; 2a/250v ac, 2a/125v ac p300 dc-13; 2a/24v dc thermal current (non switching) 1 x 8a, 2 x 7a fuses input (external) output (external) 500ma time delay 6a fast acting min. switched current/voltage 1ma/10v power on delay manual reset auto reset 40ms 200ms response time 15ms indication leds power k1 k2 green=ready, red=mat activated green=k1 closed, if k1 alone, check for short across reset button green=k2 closed operating temperature -15c to +55c (+5f 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 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?term. screws 1 nm (8 lbin) case material red polycarbonate mounting 35mm din rail weight 220g (0.485lbs) electrical life 222v 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 maximum operating frequency 1200 cycles/hour mechanical life 10,000,000 operations vibration 10g 10-55hz shock 30g, 11ms half-sine
