Product Introduction

---

The Honeywell FS-SAO-0220M is a high-performance Safety Analog Output module engineered specifically for use in safety-critical process automation systems. As part of Honeywell’s Fail-Safe Controller (FSC) family, the FS-SAO-0220M provides dual-channel isolated analog output capability, ensuring redundancy and integrity in applications requiring SIL-rated safety systems. This module is designed to interface seamlessly with field actuators and final control elements such as valves, variable speed drives, and other analog-controlled instruments.

Its robust design and precise signal processing capabilities make it suitable for use in industries such as oil & gas, refining, petrochemicals, and power generation, where compliance with stringent safety standards (such as IEC 61508 and ISA S84) is critical.

Product Advantages

---

1. Dual-Channel Redundancy: Each FS-SAO-0220M module includes two independent analog output channels, providing high reliability and enabling redundancy in safety applications.

2. Integrated Diagnostics: Advanced self-diagnostic features monitor loop integrity, detect short circuits, and identify open loop failures in real-time, improving system reliability.

3. Compliance with SIL Standards: Certified for use in SIL2 and SIL3 environments, ensuring suitability for high-demand safety functions.

4. Robust Build for Harsh Environments: With extended temperature and humidity tolerances, the module is ideal for installation in extreme industrial conditions.

5. Flexible Mounting Options: Compatible with standard Honeywell FSC chassis configurations, allowing seamless integration into existing systems.

6. Fast Response Time: The module responds quickly (<20 ms), enabling tight control loops and rapid safety responses.

7. Electrically Isolated Outputs: Ensures no cross-interference between channels and protects the system from transient disturbances.

Frequently Asked Questions (FAQ)

---

Q1: What type of signal does the FS-SAO-0220M output?
A1: The module provides a standard 4–20 mA analog output signal per channel, suitable for most industrial actuators.

Q2: Can this module be used in SIL3 safety functions?
A2: Yes, when installed in a redundant configuration, it meets SIL3 compliance per IEC 61508.

Q3: Is the FS-SAO-0220M hot-swappable?
A3: No, due to its role in safety-critical applications, the module should not be replaced while powered to maintain system integrity.

Q4: Does it support HART communication?
A4: No, this particular module does not have built-in HART capabilities. For HART, a separate compatible interface is required.

Q5: How are the output channels protected?
A5: Each output channel is galvanically isolated and has built-in diagnostics for open-loop, short-circuit, and load monitoring.

Q6: Can the module be used in hazardous areas?
A6: It is certified for installation in systems operating in hazardous environments, but should be placed within certified enclosures.

Q7: What chassis or rack is compatible with FS-SAO-0220M?
A7: It is designed for Honeywell FSC system racks, specifically the ones supporting safety I/O modules.

Q8: What’s the recommended power supply voltage?
A8: The nominal power supply is 24 VDC.

Q9: Does the module require calibration?
A9: No user calibration is typically required; it is factory-calibrated and self-monitoring.

Q10: How long is the expected service life of the FS-SAO-0220M?
A10: When operated within specified conditions, the module has an expected service life exceeding 5 years.
