Cold Junction Compensation and Channel Signal Processing
For Yokogawa process I/O applications, AMM32T is designed for analog measurement channel handling where RTD sensor inputs are converted and multiplexed through the I/O architecture. The module supports software-defined input range selection and channel configuration.
The RTD measurement path is configured for JIS JPt100 and JIS Pt100 (DIN Pt100) 3-wire sensors. The connected AMT16R provides the 16-channel interface arrangement for RTD signal acquisition.
Frequently Asked Questions
Q: What type of temperature sensors can be connected to the AMM32T?
A: The AMM32T accepts RTD inputs using JIS JPt100 or JIS Pt100 (DIN Pt100) sensors in a 3-wire configuration.
Q: How is the AMM32T installed inside the control system?
A: The module is installed in the I/O module nest and connected to the I/O module terminal using M4 screws.
Q: How is the input range configured for this module?
A: Input signal types and measurement ranges are configured through software settings rather than hardware switches.
Field Installation Guidelines
- Install the AMM32T in the designated Yokogawa I/O module nest position according to the system hardware configuration.
- Use the specified KS-series connection cables for compatible Yokogawa I/O modules.
- Ensure RTD wiring follows the 3-wire sensor connection method to maintain measurement accuracy.
- Connect cable shields according to the Yokogawa system grounding practice to reduce electrical interference.
- Separate RTD signal wiring from high-voltage power cables and high-current switching circuits.
- Verify terminal screw connections and module seating before system startup.
- Confirm software channel assignment and input range settings before enabling measurement operation.
