Description

Safety relays are designed to control several circuits simultaneously using reduced power supply or a uniform signal; best suited for commercial appliances and the telecommunications industry. Raptor Supplies offers an array of these safety relays from brands like Dayton, General Electric, Omron, Schneider Electric and Square D. Omron relays are Class 1 Division 2 approved and feature cadmium-free contacts for environment-friendly use. These relays are hermetically sealed to provide optimum protection in hazardous locations and come with plug-in terminals to ensure ease-of-installation. Square D latching relays come with straight-through wiring and plug-in contact cartridges to allow easy contact conversion and replacement. These relays further provide sequence memory in the event of power loss, thereby suitable for use with punch presses and process control devices. Choose from a wide range of these safety relays available in 50 & 60 Hz frequency ratings.
