FC-TSRO-0824 Temperature Sensing Relay Output Module Industrial Control 8-Channel 24V High Reliability

1. SIL 3-Certified Power Distribution Solution​

The Honeywell FC-TSRO-0824 is a high-integrity safety relay module engineered for critical load control in safety instrumented systems requiring SIL 3 compliance per IEC 61508. Featuring ​8 force-guided relay outputs​ with ​cross-monitored architecture, this device delivers ​​≤100ms response time​ and ​99% diagnostic coverage​ for ISO 13849-1 PL e certification. Its ​compact DIN-rail housing​ provides ​IP40 protection​ while operating across ​​-40°C to +85°C. The "0824" suffix denotes ​8 channels, ​24V DC control voltage, and ​dual-redundant power inputs. Certified for ​ATEX/IECEx Zone 2/22​ (Ex ic IIC T85°C Gc), it incorporates ​contact welding detection​ via ​current monitoring​ and ​automatic fault lockdown. Designed for emergency shutdown systems, burner management, and turbomachinery protection, this module executes vital safety functions including ​STO (Safe Torque Off)​​ and ​SS1 (Safe Stop 1)​​ with ​2A @ 230V AC​ switching capacity per channel. Integrated ​HART 7.5 communication​ enables predictive maintenance alerts for contact wear and coil degradation.

​2. Critical Technical Specifications​

This module supports ​8 independent relay channels​ with ​force-guided contacts​ (EN 50205) rated for ​2A @ 230V AC / 0.5A @ 24V DC. Electrical specifications include ​4kV impulse withstand​ (IEC 61000-4-5), ​1500V AC channel-to-channel isolation, and ​​≤10ms contact switching time. Power supply operates at ​18-30V DC ±10%​​ with ​dual redundant inputs​ and ​​≤8W consumption. Connection utilizes ​removable screw terminals​ (0.2–2.5mm²) with ​color-coded channels. Safety certifications cover ​SIL 3 (PFHD 1×10⁻⁹/h)​, ​PL e (Cat.4)​, ​ATEX/IECEx Zone 2/22, and ​UL 61800-5-1. Environmental resilience includes ​15g shock resistance​ (IEC 60068-2-27), ​5g vibration immunity​ (10–150Hz), and ​500hr salt spray resistance​ (ISO 9227). Dimensions are ​110×100×45mm​ (H×W×D) with ​500,000h MTBF​ at 40°C (IEC 61709).

​3. Safety-Critical Industrial Applications​

This module excels in high-risk process safety scenarios:

• ​Oil & Gas HIPPS: Emergency shutdown valve de-energization
• ​Power Generation: Turbine overspeed trip circuit activation
• ​Chemical Plants: Reactor pressure relief solenoid control
• ​Burner Management: Fuel valve shutdown during flame failure
• ​Compressor Stations: High-pressure trip system execution
• ​Pharmaceutical: Sterilization vessel vent valve control
• ​Water Treatment: Chlorine gas containment system activation
• ​Mining Ventilation: Methane purge system triggering
  Its SIL 3 certification enables deployment in safety instrumented functions (SIF) where undetected failure could cause catastrophic incidents. The -40°C cold-start capability supports arctic operations, while hot-swappable design allows maintenance without process interruption in 24/7 facilities. Force-guided contacts ensure mechanical cross-blocking to prevent simultaneous NO/NC closure, meeting IEC 61800-5-2 safety requirements for drive system isolation.

​4. Functional Safety Advantages​
