Product Details

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.

Rockwell Automation Monitoring Safety Relay, 230V AC Supply Voltage, 3 Safety Contacts - MSR127RP Series - 440R-N23133

Prevent sudden faults from damaging your setup with this safety relay from Rockwell Automation. It blocks output signals if a fault emerges in your electrical system to shut down the connected machinery and allow you to address the issue safely. With its single-function design, you can individually programme the relay to monitor for the faults you're most concerned about. The relay needs a manual reset after tripping, ensuring that the circuit stays off while inspection and servicing take place for maximum personnel safety.
Built-in LED indicators inform operators that the relay is activated and when a fault emerges, reducing the time spent on system inspections
Supports single and dual-channel monitoring for a versatile component that suits smaller safety applications
Switching time of 15ms provides a rapid response to stop critical faults before they become dangerous
Compatible with a light curtain sensor to keep personnel and equipment safe

Standards and Certifications

EN 954-1 and 60204-1 (European Norm)
CE (Conformitè Europëenne)

Is this safety relay suitable for use with my DIN rail-mounted system?

Yes. You can mount this relay on a 35mm DIN rail in an enclosure with a minimum IP54 (ingress protection) rating.
