Function Features
- Full Isolation Design Improves Anti-Interference Capability
All 8 output channels are galvanically isolated from each other, as well as from the ground and module logic. Each channel is also equipped with current limiting and voltage regulation functions. This design completely eliminates signal crosstalk between channels, prevents module damage caused by voltage surges or electromagnetic interference, and ensures stable signal output in complex industrial electromagnetic environments.
- Dual Signal Output and Versatile Command Support
Each channel can flexibly switch between 4 – 20mA analog signals and HART FSK digital signals, supporting mixed connection with standard analog devices and HART intelligent devices without hardware modification. It supports HART universal, common practice, and device-specific commands, enabling the DCS to not only send control signals but also obtain detailed device status and diagnostic information.
- Rugged Structure and Intuitive Status Monitoring
The extruded aluminum shell provides strong physical protection for internal circuits, allowing the module to withstand harsh conditions such as dust, vibration, and chemical corrosion on industrial sites. The front-panel LED indicators clearly display the module’s operating status and channel communication activities, enabling maintenance personnel to quickly identify and troubleshoot issues.
- Easy Integration and Long-Distance Transmission
It is fully compatible with the Compact 200 series I/O subsystem and can achieve functions previously provided by the 100 series FBM I/O subsystem when matched with appropriate termination assemblies. It supports local or remote field wiring connections via termination assemblies, and its 3030-meter maximum transmission distance fully meets the wiring requirements of large-scale industrial sites.
