Product Description:

The ELM3148-0000 is an output terminal device to be used in cases where there is a need for electrical isolation and signal transformation. It has one output channel and a phototransistor type of output, which enhances its suitability in using optical isolation to convert the input signals.

This kind of construction offers strong protection against voltage spikes as well as electrical noise. This device has a high isolation voltage of 5000 Vrms. This makes it ideal for use in applications with high potential differences between load and control sides. The ELM3148-0000 has a DC input with stable and consistent signal performance. It features a forward voltage of 1.2V and can handle a forward current of 60mA, providing consistent signal drive without wasteful power consumption. The transfer ratio is between the minimum 50% and a maximum of 600% with an input current of 10mA. The variability in this model ensures circuit flexibility in variable response or amplification applications. The collector-emitter voltage is a maximum of 80V with a high-margin protection against terminal damage from over-voltage. It enables the component to operate effectively in signal isolation, switching, and logic interfacing applications. The construction and packaging enable space-restricted applications with secure electrical performance. Single-channel design makes it easy to deploy in systems where one-to-one signal isolation is critical.

High sensitivity and low response time because of the utilization of a phototransistor lead to fast and accurate signal transmission. With balanced high isolation, wide transfer ratio, and small size, the ELM3148-0000 is ideal for industrial, automation, and embedded system applications where precise and isolated signal paths are needed. It provides reliability and safety in applications where signal integrity and isolation are critical to system performance.
