Product Details
Rockwell Automation Minotaur 440R MSR125H/HP 2 Channel Safety Relay
Achieve greater control and efficiency with the Minotaur MSR125H/HP Safety Relays by Rockwell Automation. The MSR125H/HP is a logic unit which is designed to monitor and interface two-hand control devices with a safety-related circuit.
These specialty safety relays are suitable for use with mechanical switches and the Bulletin 800Z Zero-Force Touch Buttons. They feature 2 Normally Open safety outputs which have independent and redundant internal contacts to support the safety function. The MSR125HP model has removable terminals, while the MSR125H model has fixed terminals.
How it works: The two switches must be operated within 0.5 seconds of each other. Both switches must be held down to authorise the ON state. The output will change to the OFF state if one of the switches is released. Both buttons must be released and then operated at the same time to re-start the machine.

440R-D23171 Safety Relay with Two Hand Control
The 440R-D23171 MSR125HP specialty safety relay has 2NO safety outputs, 24V dc power supply and automatic reset. It also has 1NC and 1NO inputs (two hand control). This model has removable terminals. The enclosure has an ingress protection of IP40 (NEMA 1), DIN 0470, while the terminal protection rating is IP20, DIN 0470. It offers simple installation as it can be mounted via DIN rail (35mm).
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.
