Description
The Honeywell 8U-PAOHA1 is a high-density 16-channel analog output module engineered for demanding industrial control environments. This module provides reliable 4-20 mA current outputs with integrated HART communication capabilities, facilitating seamless integration with field instruments in sectors such as power generation, oil and gas, and mineral processing. The 8U-PAOHA1 is designed for high-availability systems, featuring support for hot-swapping (insertion and removal under power) to maintain process continuity during maintenance cycles.
Features
- 16 isolated analog output channels supporting 4-20 mA signaling.
- Integrated HART protocol support for advanced device diagnostics and configuration.
- Hot-swappable design allows for module replacement without interrupting the control process.
- High-resolution digital-to-analog conversion for precise field device positioning.
- Robust electrical design capable of driving loads between 50 and 800 ohms.
- Fast response time of 80 ms to reach 1% of the final output value.
