Description
Matrix Systems 12924/13021 Programmable Quad 5x10x2 Wire Switching System 4204
The Matrix Systems Corporation 12924/13021 is a programmable quad wire switching system housed in a 4U rackmount mainframe chassis. The system uses a 5x10x2 switching architecture across four independent sections, each controlled by plug-in relay cards. The mainframe is populated with Model 4204 dual five-throw two-wire relay cards, each providing two independent five-throw relay paths with individual status LEDs visible from the front panel.

Applications
Programmable relay switching matrices like the Matrix Systems 12924/13021 are used in automated test systems, signal routing, and stimulus/response testing environments where multiple signal paths must be switched under software or hardware control. The 5x10x2 architecture allows a common bus or stimulus to be connected to any of ten output points in two-wire (sense and source) configurations — common in resistance measurement, continuity testing, functional board test, and telecommunications test setups. The parallel control interface allows integration with test controllers, ATE mainframes, and PC-based test automation platforms. Systems of this type were widely deployed in aerospace, defense electronics test, and telecommunications manufacturing test throughout the 1990s and 2000s, where repeatable, programmable signal switching was required across large numbers of test points. The wide-range AC input (85–265 VAC) makes this system compatible with both US and international lab environments.
This Matrix Systems 12924/13021 Programmable Quad 5x10x2 Wire Switching System has been inspected and is in good condition. The chassis and front panel show normal cosmetic wear consistent with lab or test environment use. All installed Model 4204 relay cards are present and seated. The front panel display windows and LED status indicators are intact. The rear panel connectors — including the IEC AC inlet, Centronics parallel ports, and the full array of RJ signal jacks — appear undamaged and clean.
