Safety Integrity Level |
SIL 3 (IEC 61508) |
The T9851 is a simplex digital output termination assembly from ICS Triplex, engineered for the AADvance safety controller platform. The T9851 provides 8 commoned output channels, interfacing field actuators such as valves, contactors, and alarms with the controller. The T9851 accepts two redundant 24 V DC field power sources and incorporates replaceable 10 A fuses for overcurrent protection. With SIL 3 certification and a compact 42 mm DIN‑rail format, the T9851 delivers reliable, high‑integrity output termination for safety‑critical industrial applications.
Emergency Shutdown Systems (ESD) – Controls shutdown valves, pump contactors, and alarm annunciators in refineries and chemical plants
Fire & Gas (F&G) Systems – Drives alarm horns and ventilation dampers in hazardous area installations
Power Generation – Operates safety shutoff valves, turbine trip relays, and motor starters
Oil & Gas Pipelines – Controls emergency isolation valves and pump interlocks
LNG & Petrochemical Facilities – Drives feed valves, discharge pumps, and safety interlocks
8 Simplex Commoned Outputs – Provides 8 non‑isolated output channels with a common return, simplifying field wiring for 24 V DC loads
Dual Redundant Field Power Inputs – Accepts two independent 24 V DC power sources (18–32 V) for high availability
Replaceable 10 A Fuses – Two field‑replaceable fuses (one per power source) protect against short circuits and overcurrent conditions
Per‑Channel Diagnostic Support – With compatible output modules (e.g., T9451), supports line monitoring, short‑circuit detection, and field power loss diagnostics
SIL 3 Certified – Certified per IEC 61508 for use in safety instrumented systems (SIS) up to SIL 3
Compact Form Factor – 42 mm width minimizes control cabinet space
Hot‑Swappable – Supports online replacement without system shutdown
SIL 3 Certified Safety Termination – Unlike generic terminal blocks, the T9851 is certified per IEC 61508 for use in safety instrumented systems, ensuring compliance with regulatory requirements for critical process applications.
Integrated Overcurrent Protection – Two replaceable 10 A fuses (one per field power source) provide dedicated protection, ensuring that a short circuit in one field actuator does not damage the expensive controller module or shut down other safety functions.
Dual Redundant Field Power – Accepts two independent 24 V DC power sources, enabling redundant power supply configurations for high‑availability systems.
Compact Footprint – The 42 mm width saves valuable cabinet space compared to larger termination assemblies, enabling higher I/O density in space‑constrained panels.
Diagnostic Ready – When paired with compatible output modules (e.g., T9451), the T9851 supports line monitoring, short‑circuit detection, and field power loss diagnostics, enabling rapid fault identification and reduced downtime.
Hot‑Swappable Design – Supports online module replacement without system shutdown, minimizing production interruptions during maintenance.
Proven ICS Triplex Quality – Backed by Rockwell Automation‘s AADvance platform, a trusted solution for safety‑critical applications worldwide.
