4-78 safety relays modular monitoring safety relays minotaur MSR221P description the MSR221P is an input expansion module for the modular minotaur msr200 family of monitoring safety relays. it can be connected to either the msr 210p or msr211p to provide additional inputs. up to 10 input modules can be connected to a 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 msr220p as well as a check on its status. the terminators must be inserted into the final output module. the input modules to a base unit can be either msr220p or MSR221P in an y combination or order. the MSR221P has two independent inputs, which can be wired in one of three ways: 1n.c., 2 n.c. or a light curtain. when connected in the 2 n.c. configuration, the MSR221P does not perform cross fault monitoring (i.e., checks for shorts between the 2 inputs). four leds provide status information on the inputs. green indicates the input is closed and red indicates the input is open. features ? 17.5mm din rail housing ? 2 input circuits: gate, e-stop or light curtains ?4 diagnostic leds ? removable terminals specifications standards iec/en60204-1, isotr12100, iso13849-1 (en 954-1), b11.19, as4024.1 approvals ce marked for all applicable directives, c-tick, tuv, culus power supply 24v dc from the base unit power consumption 2w safety inputs 1 n.c., 2 n.c., light curtain input simultaneity infinite maximum input resistance 1300ohms indication leds green = input 1 closed red = input 1 open green = input 2 closed red = input 2 open impulse withstand voltage 2500v pollution degree 2 operating temperature -5c to +55c (+23f to 131f) humidity 90%rh enclosure protection ip40 (nema 1) terminal protection ip20 conductor size 0.2?4mm 2 (24?12 awg) torque settings?terminal screws 0.4?0.5 nm (3.54?4.43lbin) case material polyamide pa 6.6 mounting 35mm din rail weight 95g (0.21lbs) vibration 10-55 hz, 0.35mm shock 10g, 16ms, 100 shocks
