ABB Safety Relays
ABB safety relays are used to control and monitor a safety device and will control the safety contacts to ensure that your machine enters a safe condition when a hazard is present. They are used for fail safe control in industrial automation applications. They are often used to monitor safety functions such as an E-Stop, safety door switch, an interlock, a light curtain or a two hand control. When any of the safety inputs are tripped it will immediately disconnect power to a hazard such as a motion or a pneumatic valve to ensure the machine will not operate and cause injury.
The ABB safety relay is compact and DIN rail mounted and is made to operate in an industrial environment. Many options are available such as LED indication, auto or manual reset, monitoring of the external feedback loop and built in timers to make setup, commissioning and troubleshooting easy while still providing a high level of safety.
FAQs
What are ABB safety relays used for?
ABB safety relays monitor safety devices and initiate safe shutdowns of machinery when unsafe conditions such as emergency stops or open guards are detected.
How are ABB safety relays different from standard relays?
ABB safety relays use redundant internal circuits and self-monitoring to ensure fail-safe operation, unlike standard relays that are not designed for safety-critical functions.
What safety devices can be connected to ABB safety relays?
Common devices include emergency stop buttons, safety switches, interlock devices, light curtains, and two-hand control systems.
Are ABB safety relays suitable for complex safety applications?
Yes, ABB offers universal and timer safety relays that support advanced safety logic and multiple safety input types.
Where are ABB safety relays typically installed?
They are installed in control panels and safety circuits for industrial machinery, automation lines, robotics cells, and material handling systems.
