ABB Jokab Sentry SSR20 Two Hand Control Safety Relay, 24V dc, 4 Safety Contacts

To ensure the safe operation of your machinery, install this safety relay from ABB Jokab. It works by simultaneously measuring the flow of current around your circuit and monitoring two input channels for connection to safety systems. In the event of a fault, it breaks the flow of current to machinery until it's safe to resume operation. A multi-reset function minimises cabling and unnecessary downtime by letting manually reset the relay, along with up to 9 other safety relays, using a single reset button.

• LEDs provide easy troubleshooting if the master control relay is switched off due to a fault
• Compatible with two-hand devices to ensure the safety of the machine operator
• Dimensions of 22.5 (W) x 120 (H) x 120mm (D) to fit into compact spaces

• Hydraulic circuits
• Assembly machines
• Clutch presses
• Welder machines

This relay latches onto a DIN rail – simply push the rear side onto the rail until you hear a click. Screw terminals allow for easy connection to other safety modules.

No, to minimise potential risks, the output is turned off as soon as the switch detects a fault.
