We just released the Si838x Isolator Family, the industry’s first high-speed, multi-channel PLC input isolators. We built them to meet the special demands of programmable logic controller (PLC) applications so they’re a compact, multi-channel, high-speed digital isolation solution for designers.
We wanted to address the many headaches designers face with PLC applications, such as high-noise environments causing optos to glitch and traditional solutions using optos that are high power, unstable, and low immunity. The Si838x Isolator Family addresses these concerns and more with an exciting new combination of high-speed channels, exceptional channel integration, bipolar input flexibility, high noise immunity, and 2.5k VRMS safety isolation previously unavailable.
Purpose-built solution for many PLC applications, the Si838x family is ideal for industrial I/O modules, computer numerical control (CNC) machines, and servo motor control as well as process automation controllers (PACs) used in distributed process control systems.
And PLC developers can now easily migrate their optocoupler-based designs to state-of-the-art digital isolation technology and take advantage of higher performance, greater design flexibility, higher channel density, and long-term reliability due to an incredible list of features:
