Littelfuse intrinsically safe relays are UL 913 listed as associated apparatuses for interfacing between hazardous and nonhazardous areas. These high-quality products protect hazardous location circuits and are core components for intrinsically safe applications. The ISS-105 series is designed as a "smart" five-channel relay and pump controller, which can be configured for pump-up or pump-down applications. The ISS-102 offers two LEDs for visual indication of relay engagement. These intrinsically safe relays are offered with single-, two-, three-, four-, or five-channel options.
