Honeywell Introduces FC-TSRO-0824 Safety Relay Output Module to Elevate Critical Process Safety Systems

In the oil and gas, petrochemical, and power industries, the reliability of Safety Instrumented Systems (SIS) is paramount, directly dictating plant safety, regulatory compliance, and operational uptime. Addressing these critical industrial demands, Honeywell has launched the FC-TSRO-0824 Safety Relay Output Module, a high-performance addition to its proven Safety Manager series. Engineered to deliver exceptional fault tolerance, rapid response speeds, and advanced diagnostic capabilities, this new module strikes an ideal balance between functional safety and cost-effectiveness for industrial automation applications of all scales.

The Importance of FC-TSRO-0824

Modern Safety Instrumented Systems (SIS)—ranging from Emergency Shutdown (ESD) and Fire and Gas (F&G) detection to critical control loops—demand uncompromising fault tolerance, seamless field integration, rigorous diagnostics, and high-density footprints. The FC-TSRO-0824 is engineered to meet these demanding environments by integrating 24 channels of safety relay outputs into a single, robust, high-density module. This design eliminates the need for external interposing relays and complex wiring, streamlining safety loop architectures.

Key Capabilities

1. The FC-TSRO-0824 integrates 24 channels of safety relay outputs (24V DC) into a single, space-saving module. Unlike standard digital output boards that depend on external interposing relays for galvanic isolation, this high-density architecture cuts hardware costs, simplifies loop design, and minimizes the overall installation footprint.

2. Equipped with built-in diagnostic intelligence, the module enables real-time monitoring of relay contact states and field wiring integrity. It continuously detects faults—such as short circuits and open loops—without requiring external monitoring hardware, maximizing system uptime and availability.

3. Engineered specifically for Honeywell’s proven Safety Manager platform, the module enables high-speed, dedicated communication with control processors. This tight integration guarantees millisecond-level response times for critical safety loops and allows comprehensive diagnostic data to be exported directly to upper-level SCADA or DCS systems.

4. Featuring heavy-duty internal relays, the FC-TSRO-0824 delivers robust galvanic isolation between logic circuits and field devices. Its fault-tolerant architecture prevents localized field wiring errors from propagating back into the controller, safeguarding the plant’s overall safety integrity.

5. Built to withstand harsh process environments, the module complies with strict international functional safety standards, including SIL 3 certification. It operates reliably under severe industrial temperatures and electrical conditions, making it an ideal solution for hazardous locations across global oil, gas, and petrochemical facilities.Please provide the next section (such as Applications, Summary, or Media Contact), and I will continue refining it to complete your news release!

Industry Applications

l Emergency Shutdown (ESD) Systems

In critical petrochemical and refinery processes, the module utilizes its 24-channel high-density safety relay outputs to drive final control elements like isolation valves and fuel trip valves. Its millisecond-level response and reliable galvanic isolation guarantee deterministic shutdown actions, mitigating catastrophic hazard risks.

l Fire and Gas (F&G) Systems

Deployed across offshore oil platforms and chemical storage facilities, the module links safety logic to field mitigation devices. It reliably triggers fire suppression systems, audible alarms, and ventilation dampers. The onboard line monitoring ensures these life-safety circuits remain intact and ready to act instantly during an emergency.

l Burner Management Systems (BMS)

For industrial boilers and furnace automation, controllers must strictly manage fuel valve sequences and ignition interlocks. The FC-TSRO-0824 provides the required SIL 3-certified fault tolerance and contact diagnostics, preventing hazardous fuel accumulation and ensuring stable combustion control.

l Critical Infrastructure & Power Generation

In power plant turbine protection and large-scale water treatment safety loops, the module monitors and controls critical trip circuits. Its deep integration with Honeywell’s Safety Manager platform enables seamless status reporting to the central control room, ensuring continuous uptime and simplified safety lifecycle management.
