Introduction
The R-9028CH is a high-precision 8-channel, 16-bit channel-isolated current output module with the following features:
- 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 features a 3000 VDC isolation design, providing robust noise immunity between the backplane and external signals, making it highly suitable for industrial environments. 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.
