All in one – Safety and control relay combined in a single device

The Eaton ESR5 NO 31 safety relay, with built in dual channel (2 Safety contacts) offers you versatile analysis of potential hazards in your machine moving environment. This model of ESR5 allows you to control all your safety devices such as emergency stops buttons, safety guards, light curtains or two handed controls. In the unlikely event there is a failure or hazard detected, the ESR5 NO 31 will work quickly to switch off the power to the machine.

What are some of the features?

• Internal logic of the safety relay will monitor your entire safety circuit and all connect peripherals such as (emergency stop buttons, safety doors or light curtains) and will run the path for you when in a fault-free state.
• This particular model offers you one or two channel variants so you can implement your safety appliances.
• In the event of a fault, the safety relay will quickly engage its primary function in cutting off power to the affected area/s.
• Detect faults before at the input level using integrated diagnostic devices.

Advantages of the ESR5 NO 31

• Narrow in width allowing you to house more important safety devices to your area where space may be an issue.
• Wide range of features offered with the device, allowing you to stay flexible and able to respond immediately to current or future changes in application requirements. This will save you cost & time in the long term.
• Many safety switching contacts and up to 5 enable and 2 signal current paths
• Approved to TÜV Rheinland, UL/CUL, CSA
• Economic monitoring
