I/O modules

Core Function of This Small Rectangular Board

The GE IS210AEPSG1AFC provides isolated DC power for Mark VIe turbines. This auxiliary power supply board converts 24 V DC into multiple output voltages. It serves critical circuits like analog inputs and digital I/O. Consequently, the module ensures clean power for sensitive control electronics.

Physical Dimensions and Board Weight

This small rectangular board measures 145 mm in length. Its width reaches 88 mm for a compact footprint. The board thickness stands at 16 mm including all components. You will find 198 discrete parts on this double-sided PCB. The GE IS210AEPSG1AFC weighs approximately 210 grams for easy handling. Its small shape fits perfectly into tight control cabinet spaces.

Output Channels and Voltage Regulation

This board delivers three isolated output voltage rails. The first rail provides 5 V DC at 1.5 A maximum. The second rail supplies ±15 V DC at 300 mA each. The third rail offers 24 V DC at 500 mA for field devices. Each rail includes overcurrent and short-circuit protection. Consequently, the module protects downstream cards from electrical faults.

Energy Storage and Component Layout

The GE IS210AEPSG1AFC incorporates four 220 µF input filter capacitors. It also uses six 47 µF tantalum capacitors on the output rails. These capacitors smooth voltage ripple during load transients. However, the board does not contain any battery backup. Total stored energy reaches approximately 0.2 joules at full charge. This low storage eliminates residual voltage hazards quickly.

Interface Connectors and Wiring Details

A single 20-pin latching header accepts the primary 24 V DC input. Furthermore, three separate 4-pin connectors deliver the output voltages. Each connector uses keyed housings to prevent miswiring. The board also includes one 2-pin jumper for enable control. Gold-plated contacts resist corrosion in industrial environments.

Installation and Compatibility Notes

You must mount this board on a DIN rail inside the Mark VIe cabinet. The module works with any 24 V DC Class 2 power source. Always connect the input ground before applying power. Then, verify each output voltage with a multimeter. The board operates reliably from -20°C to +60°C ambient temperature.
