>> Key Advantages & Features
16-Channel Independent Control
Featuring 16 isolated output channels, each capable of independent configuration and operation, the module supports simultaneous control of multiple process variables. This design reduces system complexity by eliminating the need for multiple single-channel modules, cutting installation space by up to 40% in control cabinets—ideal for large-scale plants with dense I/O requirements.
High-Precision Signal Output
Delivers 4-20 mA output signals with ±0.05% full-scale linearity and ±0.35% calibration accuracy at 25°C. Even in temperature fluctuations (-40°C to 70°C), its temperature drift remains as low as 0.005%/°C, ensuring stable control of critical processes like flow regulation in petroleum pipelines or pressure management in chemical reactors.
HART Protocol Integration
Built-in HART communication enables two-way data exchange between the module and HART-enabled field devices. This allows remote calibration, diagnostics, and parameter adjustment without interrupting operations, reducing maintenance downtime by 30% compared to non-HART modules.
Enhanced Safety & Reliability
Supports channel-level "Failopt" configuration, allowing users to set each channel to either hold the last value or switch to a predefined safe state during faults. Additionally, it features open-circuit detection with real-time alerts, ensuring rapid response to wiring issues in safety-critical applications like pharmaceutical batch processing.
Redundancy Support
Compatible with redundant system architectures, the module can be paired with a backup unit for seamless failover. This design achieves 99.999% availability, making it suitable for uninterrupted processes such as power plant turbine control or continuous chemical production.
