Frequently Asked Questions
What is the function of a safety relay?
A safety relay is a device that implements safety functions. In the case of the UE10-3OS2D0, it is used to monitor a variety of safety devices such as emergency stop buttons, safety guards, light curtains, and more, ensuring that these safety circuits operate correctly and provide the necessary protection for both machinery and personnel.
Can this safety relay be integrated with other safety systems?
Yes, the UE10-3OS2D0 can be integrated with other safety systems. It is designed to work in conjunction with a variety of safety devices and can be part of a larger safety network within an industrial setting.
What types of outputs does this safety relay support?
The UE10-3OS2D0 supports several output configurations including normally open (NO) safety outputs and normally closed (NC) auxiliary outputs, which can be used for indicating the status of the safety circuit and for diagnostic purposes.
How does one determine the safety category of this relay?
The safety category of the relay is determined by the standards it meets, such as EN ISO 13849 or IEC 61508. The UE10-3OS2D0 is designed to meet high safety standards, typically achieving a Category 4 / PLe according to EN ISO 13849, which is suitable for the highest level of safety for control systems.
What is the typical response time for this safety relay?
The typical response time for the UE10-3OS2D0 safety relay is less than or equal to 20 milliseconds, which allows for quick reaction to any safety incidents, minimising potential hazards.
What is the expected service life of this safety relay?
The expected service life of a safety relay like the UE10-3OS2D0 depends on the number of operating cycles it can perform. It has a mechanical life expectancy of up to 10 million operating cycles and an electrical life expectancy of up to 2 million operating cycles under specified conditions.
