Velan APS Rev C Modem Card PCB Module with RJ11 Connector

Velan APS Rev C Modem Card PCB Module with RJ11 Connector

The Velan APS Rev C is a proprietary modem card PCB module designed for embedded or integrated modem communication functions. The board carries a revision designation of Rev C, silkscreened directly onto the PCB, and includes an attached RJ11 connector on a short wire harness — the standard interface for analog phone-line modem signaling. Several ICs and logic chips are populated on the board, including a Harris/Intersil DIP package processor visible on the component side.

Applications

The Velan APS modem card is a proprietary embedded modem module, the type commonly used in specialized industrial, point-of-sale, or legacy OEM systems from the late 1980s through the 1990s that required built-in analog dial-up modem capability. Cards of this type were integrated into host systems — such as industrial controllers, proprietary terminals, or dedicated communication appliances — to provide dial-up telephone network connectivity without an external modem. The RJ11 interface connects directly to a standard analog phone line. Today these cards are primarily sought as replacement parts for legacy systems that rely on this specific modem module to maintain their original communication function.
