Weidmüller 800779 Opto Coupler Module EG03 12-28VDC 50KHz 24V

The Weidmüller 800779 EG03 Opto Coupler Module is a solid-state interface module that provides electrical isolation and high-speed signal switching for industrial automation systems. It accepts a 12–28VDC input with a nominal control voltage of 24VDC and supports switching up to 50 kHz, using optical isolation and solid-state electronic switching. An integrated LED status indicator, reverse polarity protection, and varistor protection help indicate operation and protect the module in demanding environments, and the unit is designed for DIN rail mounting in PLC cabinets, process controllers, and automation equipment. Common applications include signal isolation and high-speed interfacing in machine controls, process automation, and industrial communication systems within PLCs and control panels.
