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.

440R-N23130 Safety Relay

The 440R-N23130 MSR127RP/TP safety relay has 3NO immediate safety outputs and 1NC immediate auxiliary output. It also has removable (screw) terminals. The power supply for this model is 230V ac. The enclosure has an ingress protection rating of IP40 (NEMA1), and the terminal protection is IP20. This safety relay can be DIN rail mounted (35mm), allowing effortless installation.

What are Safety Relays?

Safety relays are devices which are used to detect errors or faults in a machine safety system, and can implement safety commands when they identify these errors to bring the risk down to an acceptable level. By doing this, they defend against hazards which could cause injury to personnel and damage to machinery. Single function relays manage one specific function, while multi-function relays can oversee different activities. Safety relays can also be connected to each other. They are often used in industrial environments such as factories, as part of a safety control circuit for dangerous machines. Typical applications include: safety mats, emergency stop push-buttons, light curtains, and magnetic switches. Rockwell Automation offer high-quality, reliable safety relays which give exceptional performance and ensure maximum protection and productivity.
