System Role
Control function
- Converts 4~20 mA process signals into system-ready data in K-series I/O racks.
- Provides both nonredundant and redundant operation modes according to station configuration.
- Supports high reliability operation with channel diagnosis and protected short-circuit behavior.
Reliability behavior
- Namur diagnosis and board diagnostics support operational status visibility.
- Channel anti-mixing pin and hot plug design support safe maintenance and serviceability.
- Short circuit, open circuit, and underrange conditions are covered by built-in fault diagnosis.
Compatibility
- Family sibling with HART version: K-AIH03, which adds HART 5 communication.
- Shares K-series I/O architecture and can be paired with corresponding K-series AI base and terminal modules.
- Channel diagnosis and redundancy behavior align with K-series redundant/nonredundant operation workflows.
Applications
- Analog current loop signal collection in process plants and DCS networks.
- Field instrumentation systems requiring 16-point current input density.
- Environments requiring anti-220VAC channel robustness and short-circuit protection.
FAQ
What is K-AI03 used for?
