The module incorporates a redundant, safety-related processor system, enabling self-testing directly on the module. All tests are executed internally; detected errors are flagged for user evaluation.

• A/D Converter Linearity: Verify accuracy across the input range.
• A/D Converter Overflow: Detect numerical saturation conditions.
• Channel Cross-Talk: Check interference between the eight input channels.
• Input Filter Function: Confirm proper signal conditioning.
• I/O Bus Communication: Validate data transfer integrity.
• Microcontroller Self-Tests: Verify core processor functionality.
• Memory Tests: Check program and data memory integrity.

• Any recognized error sets the channel error bit.
• Evaluation and response must be implemented within the user program.

• Each part has a one-year warranty.
• Warranty terms may vary based on supplier agreements.

• Standard carriers: FedEx, UPS, DHL, USPS.
