• Current Output Range: 4 ~20mA current output (Source Type)
• High Accuracy: Tolerance ±0.05% FSR to ensure accurate current output.
• Power-on value & Safety value: Ensures that the module outputs a predefined current during startup or abnormal conditions.
• Channel Isolation: The electrical signals between channels are completely isolated to ensure that the channels do not interfere with each other.
• Channel Disconnection Detection: Ensure the safety and stability of channel wiring.
• HART Communications: Built-in HART master communication for accessing HART device information.
• LED Indicator: Displays channel abnormal status and module operation status.

The R-9028CH module must be used with a terminal board to connect external signals and supports a terminal board disconnection detection mechanism to ensure wiring stability. It provides 3000 VDC isolation between the power supply and the backplane bus, making it better able to prevent noise interference in industrial environments without affecting the RIO-98x0 system. Additionally, the module supports a redundancy design, allowing the system to continue stable operation even if a single I/O module fails, further enhancing system reliability.
