Use this safety relay from Phoenix Contact to reduce risks in industrial applications. The component is used with emergency-stop buttons and safety doors to initiate a safe and prompt response when a hazard occurs, preventing damage to equipment and harm to operators. It has a wide inrush current capacity between 25mA and 6A to conveniently accommodate a variety of connected devices.
This component's compact dimensions of 99 (length), 22.5 (width) and 114.5mm (depth) make it a space-saving solution for setups with limited room. It has a green LED (light-emitting diode) indicator that lets you quickly check its status when a fault occurs. For transient voltage protection, it also has a suppressor diode that clamps surge voltages before they can damage the system, enhancing electrical safety. You'll find this relay used in factories and on assembly lines where safety is a priority.
