6. Selection Recommendations

• Compatibility: Ensure compatibility with your GE PLC system (e.g., Series 90-30/70).
• Environment: Rated for -40°C to +70°C ambient temperature; suitable for harsh industrial settings.
• Channels: Choose 8-channel configuration for cost-effective small-scale projects; scale with additional modules for larger systems.
• Budget: Balances performance and cost, offering a 20% lower total cost of ownership over premium alternatives due to reduced maintenance.

7. Precautions

• Installation: Follow DIN-rail mounting guidelines; ensure proper grounding to prevent noise interference.
• Sensor Wiring: Use shielded cables (24AWG or thicker) for long-distance installations (>50m).
• Calibration: Factory-calibrated; periodic re-calibration (every 2 years) recommended for critical applications.
• Safety: Disconnect power before module replacement; comply with IEC 61131-2 safety standards.
