Sep 29, 2008 Featuring integral photoelectric sensor combined with light feedback compensation circuitry, 10 Series prevents controlled lighting from hunting on/off due to perceived increase in ambient light when lights are turned on. Series includes single-pole and 2-pole output types rated at 16 A, and miniature Model 10.51, with single 12 A output. Ambient light switching level is adjustable from 1-80 lux, and relays are capable of switching up to 2.3 kW of incandescent or halogen lighting.

Jul 17, 2008 Single-channel Series SLD monitors shaft seal of submersible pump to detect leak before pump failure. Leak is detected by sensing status of float or conductivity switch installed in seal cavity. When resistance drops below set sensitivity, output relay energizes and LED indicator illuminates. Utilizing 120 Vac control voltage, relays offer sensitivities of 470 W fixed, 470 to 10 kW adjustable, and 4.7 k to 100 kW adjustable.
