Rockwell Automation 440R Minotaur MSR127RTP Safety Relay, Single Channel


For dependable fault detection that will minimise downtime and help you keep operations running efficiently, the 440R Minotaur MSR127RTP Single Function Safety Relays by Rockwell Automation are the ideal choice for your safety control system. The MSR family of relays are perfectly suited for relatively small safety applications and single zone control.

These versatile single function safety relays can be connected in 3 different input wiring configurations: 1NC, 2NC, or with two PNP connections from a light curtain. The MSR127RT checks for cross faults across the two inputs when connected in the 2NC configuration. The light curtain must perform the cross fault detection when the safety relay is connected to light curtains.

The MSR127TP relay features an automatic/manual reset, which can be jumpered or changed to an unmonitored manual reset by the addition of a normally open switch in the monitoring loop. The MSR127RP unit has a monitored manual reset which offers checking of the output monitoring circuit.

These devices are ideal for light curtain, E-stop or safety gate applications.

Features and Benefits:


• Compact housing
• Stop category 0 and Cross fault monitoring
• Cat. 4 per EN954-1
• Relays with monitored or automatic reset
• Removable terminals
•Three NO (Normally Open) safety-rated outputs, one NC (Normally Closed) auxiliary contact
• Safety outputs feature independent and redundant internal contacts to support the safety function
• Auxiliary output is a non-safety output which can provide an external signal to indicate the status of the safety outputs

Standards:


EN 954-1, ISO 13849-1, IEC/EN 60204-1, IEC 60947-4-1, IEC 60947-5-1, ANSI B11.19, AS4024.1.
