Product Description

The TK-HAO081 is a high-precision 8-channel analog output module designed for the Honeywell HC900 Process & Safety Controller system. It provides isolated analog outputs to drive field devices such as variable frequency drives (VFDs), control valve positioners, and actuators. Each channel is independently configurable for voltage or current signals, offering flexibility for diverse instrumentation.

Built for mission-critical applications, the module delivers 16-bit resolution and sub-1 ms loop update times, ensuring rapid and precise response in high-speed control loops. Onboard diagnostics continuously monitor channel health and output integrity, supporting proactive fault detection and minimizing system downtime. Its modular, plug-and-play design allows seamless integration into HC900 chassis while maintaining industrial-grade reliability and scalability.

    Generating reference signals for system calibration and instrument testing.

  • Safety System Feedback
    Driving local analog indicators or recorders within SIL-rated loops.

Frequently Asked Questions

Q: Can the TK-HAO081 handle different signal types simultaneously?
A: Yes. Individual channels can be configured for voltage or current outputs via HC900 software, allowing flexible interfacing with various field devices.

Q: Does the module detect loop failures?
A: Yes. Onboard diagnostics monitor each output loop. If a channel experiences an open circuit or fails to reach its setpoint, the module can trigger a system alarm for immediate troubleshooting.
