4-82 safety relays modular monitoring safety relays minotaur MSR238 description the MSR238 is an time-delayed output expansion module for the modular minotaur msr200 family of monitoring safety relays. it can be connected to either the msr210 or msr211 base unit or to the msr230output module to provide time-delayed outputs. up to 2 output modules can be connected to one base unit by simply removing the terminator, included with each base unit, and connecting the ribbon cables of the neighboring module. the connecting ribbon cable provides power to the MSR238 as well as a check on its status. the terminators must be inserted into the final output module. the MSR238 has two safety rated outputs that work in parallel with the safety outputs of the base unit. when the output of the base unit is activated, the outputs of the MSR238 are the user-selected time delay expires. the time delay is set by connecting jumpers to the wiring terminals. the outputs are 2 normally open safety rated outputs. the safety outputs have independent and redundant internal contacts to help ensure the safety function. the delayed normally closed output is an auxiliary signal that must only be used to indicate the status of the MSR238. features ? category 3 per en 954-1 ? stop category 1 ?2 diagnostic leds ? removable terminals ?2 n.o. delayed safety outputs ?1 n.c. delayed aux. output 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 60947-4-1, iec 60947-5-1, ansi b11.19, as4024.1 approvals c-tick, ce marked for all applicable directives, culus and tuv category cat. 3 per en954-1 (iso13849-1) power supply 24v dc from the base unit power consumption 2.5w fuses output (ext. recommended) 6a slow blow or 10a quick blow outputs 2 n.o. safety 1 n.c. auxiliary output utilization per iec 60947-4-1 (resistive) ac-1: 6a/250v ac dc-1: 6a/24v dc ? output utilization per iec 60947-5-1 (inductive) b300, ac-15 3a/250v ac, 3a/125vac p300, dc-13 2.5a/24v dc thermal current (non switching) 1x6a, 2x4a min. switched current/voltage 10ma/10v dc contact material agsno 2 with 2 micron gold plating indication leds green = ch1 output active green = ch2 output active impulse withstand voltage 2500v pollution degree 2 operating temperature -5c to +55c (+23f to 141f) humidity 95% rh enclosure protection ip40 (nema 1) terminal protection ip20 maximum conductor size 0.2 ? 2.5mm 2 (24-12 awg) torque settings?term. screws 0.4 ? 0.5 nm (3.54 ? 4.43 lb2in) case material polyamide pa 6.6 mounting 35mm din rail weight 215 (0.47lbs) 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 mechanical life 10,000,000 cycles vibration 10-55 hz, 0.35mm shock 10g, 16ms, 100 shocks
