Working Principle

The module receives analog signals from field instruments, conditions the signals through filtering and amplification circuits, and converts them to digital values via a high-resolution A/D converter. The digital data is transmitted to the C300 controller over the I/O link for process control, alarm management and data logging.

Installation Requirements

• Plug into corresponding Series C IOTA (Input Output Terminal Assembly) base
• Field wiring connects to two-level detachable terminals on the IOTA
• Power is supplied through the IOTA backplane; no external power supply required
• Mount vertically in control cabinet for optimal heat dissipation and wiring access
• Configure jumper settings for each channel according to voltage or current input type

Usage Precautions

• Verify jumper configuration before applying field signals to avoid module damage
• Do not exceed the maximum input voltage or current ratings
• Ensure proper grounding of the IOTA and cabinet to minimize electromagnetic interference
• Follow ESD handling procedures when installing or removing the module
• Perform regular inspection of terminal connections to prevent signal drift
