Yaskawa JAMSC-B1050 Memocon-SC Output Module
Yaskawa JAMSC-B1050 Memocon-SC Output Module
The Yaskawa JAMSC-B1050 is a vintage AC output module designed for the Memocon-SC series of Programmable Logic Controllers (PLCs).
This series was one of Yaskawa’s primary automation platforms during the 1980s and 1990s, widely known for its ruggedness in industrial environments.
The JAMSC-B1050 serves as the interface between the PLC’s logic and high-voltage AC field devices, such as solenoid valves, motor starters, and indicator lights.

Product Advantages and Features
High Noise Immunity: Specifically designed for the “2000 Series” I/O architecture, which features robust filtering to operate near heavy machinery and high-voltage power lines.
Direct AC Switching: Eliminates the need for interposing relays when controlling standard 100V AC industrial loads, simplifying cabinet wiring.
Diagnostic Indicators: Front-panel LEDs provide immediate visual status of each output point, significantly reducing troubleshooting time.
Modular Reliability: Part of a proven ecosystem used globally in “zero-fail” environments like steel production and maritime automation.
Ease of Replacement: The module is designed for quick insertion and removal from the standard Memocon-SC backplane.
