FC-TSDO-04UNI Temp Sensing Digital Out Universal Module Industrial 4-Channel Stable

1. SIL 3-Certified Configurable Output Solution​

The Honeywell FC-TSDO-04UNI is a high-integrity safety output module engineered for critical load control in SIL 3 safety instrumented systems per IEC 61508. Featuring ​4 universal configurable channels​ with ​dual-redundant architecture, this device supports ​PNP/NPN, relay, or Namur outputs​ with ​​≤100ms response time​ and ​99% diagnostic coverage. Its ​compact DIN-rail housing​ provides ​IP40 protection​ while operating across ​​-40°C to +85°C. The "04UNI" suffix denotes ​universal channel configurability, ​24V DC control voltage, and ​dual-redundant power inputs. Certified for ​ATEX/IECEx Zone 2/22​ (Ex ic IIC T85°C Gc), it incorporates ​cross-monitored processors​ with ​​≤50µs fault detection​ and ​contact welding detection. Designed for emergency shutdown systems and turbomachinery protection, this module executes ​STO (Safe Torque Off)​​ and ​SS1 (Safe Stop 1)​​ functions with ​2A @ 230V AC / 4A @ 30V DC​ switching capacity per channel. Integrated ​HART 7.5 communication​ enables predictive maintenance alerts and remote configuration.

​2. Critical Technical Specifications​

This module supports ​4 independently configurable channels​ with output options:

• ​PNP/NPN transistor: 2A @ 30V DC
• ​Electromechanical relay: 2A @ 230V AC (EN 61810-1)
• ​NAMUR NE44: 8mA sink/source
  Electrical specifications include ​4kV surge protection​ (IEC 61000-4-5), ​1500V AC isolation, and ​​≤10ms switching time. Power supply operates at ​18-30V DC ±10%​​ with ​dual redundant inputs​ and ​​≤6W consumption. Connection utilizes ​removable screw terminals​ (0.2–2.5mm²) with ​color-coded channels. Safety certifications: ​SIL 3 (PFHD 1×10⁻⁹/h)​, ​PL e (ISO 13849-1 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: ​110×75×45mm​ (H×W×D) with ​500,000h MTBF​ at 40°C (IEC 61709).

​3. Flexible Safety-Critical Applications​

This module excels in diverse safety scenarios:

• ​HIPPS Systems: Emergency valve de-energization in oil/gas
• ​Turbine Protection: Overspeed trip circuit activation
• ​Burner Management: Fuel valve shutdown during flame failure
• ​Chemical Reactors: Pressure relief solenoid control
• ​Robotic Cells: Safe torque off (STO) for collaborative robots
• ​Pharmaceutical: Sterilizer vent valve control
• ​Water Treatment: Chlorine containment system activation
• ​Mining Ventilation: Methane purge triggering
  Its universal channel configuration replaces multiple discrete modules, reducing cabinet space by 60%. SIL 3 certification supports Safety Instrumented Functions (SIF) with ​PFDavg 0.0001. The -40°C cold-start capability enables arctic operations, while hot-swappable design allows maintenance without process interruption. Each channel can be configured independently via software for PNP, NPN, relay, or NAMUR outputs – enabling seamless integration with valves, contactors, and intrinsically safe barriers.
