0451385108 - ABB Jokab Sentry SSR10 24VDC Safety Relay

Keep Your Shop Safe and Compliant

Safety is the number one priority in any welding shop or fabrication facility. The ABB Sentry SSR10 Safety Relay 24VDC is an essential component for maintaining the safety systems on your welding power sources, robotic cells, and cutting tables. If your machine's emergency stop circuit is acting up or the safety relay has failed, the SSR10 is the direct, high-quality replacement you need to get your equipment back up and running safely. This relay acts as the brain of your safety system, constantly checking that E-stops are released and gates are closed before allowing the machine to operate.

Easy Installation and Troubleshooting

We know that downtime costs money. That's why the Sentry SSR10 is built for speed and simplicity. It snaps directly onto a standard DIN rail inside your machine's control cabinet. The removable terminal blocks mean you don't have to unscrew every single wire to swap out a unit—just unplug the blocks from the old unit and plug them into the new one. The bright LEDs on the front panel tell you exactly what's going on: green means go, and red indicates a fault. This instant feedback helps you figure out if the problem is the relay itself or a loose wire on an E-stop button somewhere on the floor.

Robust Protection for Heavy Machinery

Welding environments are tough on electronics, but ABB components are built to last. The SSR10 handles the 24VDC control power common in most modern welders and plasma cutters. It features 3 safety contacts to cut power to the heavy stuff (like the welding arc or motor drives) and 1 signal contact to tell your controller that the machine is in a safe state. Whether you are retrofitting an older machine with better safety gear or repairing a modern system, this relay gives you the peace of mind that your safety circuit meets the highest standards (SIL3/PLe).

Versatile Reset Options

Every shop setup is different. The SSR10 allows you to choose between automatic reset (the machine is ready as soon as the safety issue is cleared) or manual reset (requiring an operator to press a reset button). This flexibility ensures that you can configure the safety logic to match your specific workflow and safety protocols, preventing accidental restarts and keeping your welders safe.
