SOLID STATE 80-219310-90 Industrial PCB Circuit Board

Application Scenarios

In a manufacturing facility running GE Fanuc Series 90-30 PLCs, engineers encountered a sudden failure of a 16-channel DC output module (IC693MDL940), causing an entire assembly line to halt. The root cause was traced to a failed internal circuit board—specifically the SOLID STATE 80-219310-90, which serves as the “heart” of the output module, controlling 16 optically isolated solid-state relay channels . Replacing the faulty board with the SOLID STATE 80-219310-90 restored full functionality within 30 minutes, eliminating a potential 8-hour downtime that could have cost over $100,000 in lost production.

Another critical application involves Westinghouse (now Eaton/Cutler-Hammer) A/DA/DAF series low-voltage air circuit breakers. Here, the SOLID STATE 80-219310-90 functions as the solid-state trip unit’s core control board, responsible for real-time current measurement, protection logic calculation, and trip actuation . It replaces older thermal-magnetic trip mechanisms with digital precision, enabling configurable long-time (L), short-time (S), instantaneous (I), and ground-fault (G) protection curves. This capability allows engineers to precisely coordinate protection settings with downstream devices, eliminating nuisance tripping while maintaining safety compliance.

Technical Principles and Innovative Values

The SOLID STATE 80-219310-90 distinguishes itself through its application-optimized design and digital protection technology.

• Innovation Point 1: Application-Specific Design with Dual Functionality
  The SOLID STATE 80-219310-90 is not a generic PCB but a purpose-built assembly designed for specific original equipment manufacturer (OEM) applications . In GE Fanuc applications, the board integrates 16 optically isolated solid-state relays, each capable of handling 0.5A continuous DC loads at 24-48V DC, with response times significantly faster than mechanical relays and no contact wear . In Eaton/Cutler-Hammer applications, it functions as a smart trip unit with integrated microprocessor and current sensor interface, enabling digital RMS current measurement .
• Innovation Point 2: Digital Precision vs. Analog Drift
  The SOLID STATE 80-219310-90 replaces older thermal-magnetic trip mechanisms with digital intelligence. Traditional bimetal-based protection suffers from calibration drift due to temperature changes and mechanical fatigue. This board uses high-speed current sampling and true RMS calculation to accurately distinguish between actual fault currents and normal inrush currents (such as motor startup), dramatically reducing nuisance tripping . Protection curves are field-configurable through the breaker’s keypad or handheld programmer—a capability impossible with mechanical designs.
• Innovation Point 3: Industrial-Grade Reliability in Harsh Environments
  Constructed on high-quality FR-4 epoxy glass substrate with precision-etched copper traces and gold-plated contacts, the SOLID STATE 80-219310-90 operates reliably across a -20°C to +85°C temperature range . The through-hole mounting design provides superior mechanical strength and thermal dissipation compared to surface-mount alternatives, making it suitable for high-vibration industrial environments. UL, CE, and RoHS certifications confirm compliance with international safety and environmental standards .
