Features:

  • Dual-Module Redundancy for SIL 3
  • Integrated 10A Field Power Fusing with Easy Access
  • Polarized Coding to Prevent Installation Errors
The ICS TRIPLEX T9852 accommodates two T9451 output modules in a single assembly. This 1oo2D (1 out of 2 with diagnostics) architecture ensures that if one output module fails, the second maintains the safety function without process interruption, meeting SIL 3 requirements for energize-to-action final elements.

Unlike standard terminal blocks, the ICS TRIPLEX T9852 includes two dedicated 10A fuses (one per field power supply) to protect against field wiring shorts. The fuses are field-replaceable without removing the termination assembly or the I/O modules, minimizing Mean Time To Repair (MTTR) in critical environments.

The ICS TRIPLEX T9852 features mechanical coding pins that align with corresponding sockets on the T9451 module. This polarization keying prevents incorrect mating of analog or other module types, ensuring that only digital output modules can be installed, thereby eliminating dangerous configuration errors.

The T9852 ICS Triplex Digital Output Termination Assembly still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • IEC 61508 SIL 3: TÜV Rheinland certified for use in safety loops up to SIL 3 (requires dual T9451 modules).
  • ATEX/IECEx Zone 2: Certified for potentially explosive gas atmospheres (II 3G Ex ec IIC T4 Gc).
  • UL Class I Division 2: Approved for hazardous locations in North America (Groups A, B, C, D).
  • RoHS Compliant: Lead-free manufacturing meets EU environmental standards.
  • Dual-Bus Backplane for High-Speed I/O Processing:The Siemens 6ES7400-1JA11-0AA0 integrates separate communication and peripheral buses, eliminating data congestion between the CPU and I/O modules. This ensures deterministic scan times for critical processes.
  • 9-Slot Density for Space-Saving Configuration:With exactly 9 slots, the Siemens 6ES7400-1JA11-0AA0 offers an ideal balance between expansion capacity and cabinet footprint. It allows you to build powerful control systems without wasting valuable panel space.
  • Redundant Power Supply Ready for Non-Stop Operation:The Siemens 6ES7400-1JA11-0AA0 supports dual power supply installation. If the primary unit fails, the backup takes over instantly, maximizing system uptime for continuous production lines.
  • Aluminum Construction for Passive Cooling:Made of industrial-grade aluminum, the Siemens 6ES7400-1JA11-0AA0 dissipates heat efficiently. This passive thermal management reduces the need for forced cooling, lowering energy costs while maintaining reliability from 0°C to 60°C.
  • Emergency Shutdown Systems (ESD): Provides high-integrity output termination for solenoid valves in oil & gas wellheads.
  • Burner Management Systems (BMS): Controls dual-block bleed valves in furnace applications requiring SIL 3 fault tolerance.
  • Fire & Gas Detection (F&G): Interfaces T9451 outputs to alarms and deluge valves in petrochemical facilities.
  • Turbine Control: Manages governor actuator outputs and overspeed protection circuits in power generation.
Description
The ICS TRIPLEX T9852 serves as the physical interface between the T9451 digital output modules and field actuators in high-integrity safety systems. Engineered for the Rockwell Automation AADvance controller, this termination assembly supports dual-module redundancy, ensuring that a single point of failure does not compromise your safety function. It is the preferred choice for emergency shutdown (ESD) and burner management systems (BMS) where high availability is mandatory.

Built with non-isolated 8-channel dual configuration, the ICS TRIPLEX T9852 accepts two independent 24 Vdc field power supplies, each protected by a replaceable 10A fuse. This design allows for hot-swapping of faulty output modules without interrupting the process, drastically reducing maintenance downtime in critical processes.

Whether you are upgrading a legacy ICS system or building a new SIL 3 solution, the ICS TRIPLEX T9852 offers a drop-in compatible interface with standard 16 AWG field wiring. Its compact form factor and robust -25°C to +70°C operating range make it suitable for harsh environments from oil refineries to power generation plants.

Technical notes
ICS TRIPLEX T9852 requires a dedicated pair of T9451 output modules to achieve SIL 3 for "energize-to-action" loops; operation in simplex mode (single T9451) degrades the safety integrity to SIL 2. Engineers must verify that the field power supply is current-limited or protected by an external 10A breaker, as the ICS TRIPLEX T9852 utilizes non-redundant fusing per power rail.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can the ICS TRIPLEX T9852 support 16-channel digital output modules?
No, the ICS TRIPLEX T9852 is strictly designed for 8-channel T9451 digital output modules. If you require 16 channels in a dual configuration, you must use two T9852 assemblies. The termination assembly’s bus structure does not support 16-channel mapping for safety outputs.
What happens if one of the 10A fuses blows on the ICS TRIPLEX T9852 while the plant is running?
The ICS TRIPLEX T9852 uses two independent fuses (one per field power supply). If one fuse blows, the corresponding T9451 module loses field power, but the redundant module (fitted in the same TA) continues to drive the outputs. The controller will generate a "Field Power Fault" diagnostic alarm, but the safety function remains available (degraded to SIL 2).
Is the ICS TRIPLEX T9852 compatible with the newer AADvance Workbench 2.x firmware?
Yes, the ICS TRIPLEX T9852 is fully compatible with AADvance system release 1.40 and all Workbench 2.x versions. It uses passive backplane communication; no firmware upgrade is required for the termination assembly itself. However, ensure your T9451 modules are on firmware revision v2.1 or higher for proper diagnostic reporting.
Can I install the ICS TRIPLEX T9852 in a Class I Division 2 hazardous area without an external fuse holder?
Yes, the ICS TRIPLEX T9852 is UL-listed for Class I, Division 2, Groups A, B, C, and D hazardous environments. The onboard 10A fuses are rated for 125 Vdc and meet the isolation requirements for hazardous locations, provided the external field power supply is connected through an approved isolation transformer per NEC/CEC standards.
