440R-C23139 Single Function Safety Relay

The 440R-C23139 unit is dual channel and has a 24 V dc power supply and removable (screw) terminals. It has 3NO immediate safety outputs, and 2 NC, 2 PNP Solid State immediate auxiliary outputs. The rated impulse withstand voltage is 2500V. The enclosure is IP40 (NEMA 1) rated and the terminals are protected to IP20. It has an operating temperature of -5°C to +55 °C (23…131 °F). Reset is configured Automatic/Manual or Manual Monitored Reset. This type of relay is the most economical solution for smaller machines.

Inputs: 1 N.C., 2 N.C., Light Curtain, Safety Mat

What are Safety Relays?

Safety relays are monitoring devices which are used to continuously check for errors or faults in a machine safety system, and can implement safety commands when they detect 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.
