Description

Product Overview

The AEIC-7272-S16 is a solid-state relay (SSR) or isolated switching module from Littelfuse (formerly part of the IXYS/Clare product line). The AEIC series provides galvanically isolated AC/DC switching with zero-crossing turn-on for low EMI. The S16 suffix indicates a 16-pin DIP package with specific voltage/current ratings. This device is designed for industrial control, instrumentation, and telecom switching applications.

  • Zero-crossing turn-on minimizes inrush current and EMI
  • LED input for direct MCU/digital logic drive
  • 16-pin DIP package compatible with standard IC sockets
  • High reliability with no moving contacts

Applications

  • Industrial process control and automation
  • Instrumentation and measurement switching
  • Telecom line switching and supervision
  • AC/DC load control from digital logic
  • Medical equipment isolation switching

The AEIC-7272-S16 is a solid-state relay module providing galvanically isolated AC/DC switching with zero-crossing turn-on. With 3750V RMS isolation between the LED input and the output switch, it enables safe digital logic control of AC/DC loads. The zero-crossing feature minimizes inrush current and EMI by only turning on near the zero voltage crossing point. The 16-pin DIP package is compatible with standard IC sockets for easy prototyping and replacement in industrial control applications.

The AEIC-7272-S16 operates as an optically coupled solid-state relay. The input side consists of an infrared LED that is driven by the control signal (typically 5-15mA from a digital output). When the LED is energized, it emits infrared light that crosses the optical isolation barrier to a photodetector array on the output side. The photodetector drives a zero-crossing detector circuit that only enables the output triac/SCR switch when the AC line voltage crosses zero. This zero-crossing turn-on eliminates the sudden voltage step that would otherwise cause high inrush currents in resistive loads or generate electromagnetic interference. The output switch (triac or back-to-back SCRs) can conduct in both directions for AC load control. The 3750V RMS isolation between input and output provides safety isolation for controlling mains-powered loads from low-voltage logic circuits. The absence of mechanical contacts means no contact bounce, no arcing, and unlimited switching cycle life.
