Littelfuse LLC44A5A is a 4A resistive output load rating power relay with a termination type of Octal 8-pin plug-in. It supports both 240V and 28V (DC) output loads and 1/10 hp @ 240V. The input AC line frequency is 50/60Hz, with a tolerance of -0.3%. It provides surge protection according to the IEEE C62.41-1991 Level A standard. The sense resistance is adjustable up to 250Ω, and sense voltage is 12V at probe terminals. It features an ON/OFF control type with a built-in time delay to prevent rapid cycling. The sense resistance tolerance is 1 kΩ ±500 at the low end and 250 kΩ ±25% at the high end.
