The search for “Triconex 9786-110” has yielded some specific, albeit fragmented, information from various technical documents and vendor listings. I was not able to find a complete datasheet, but I have enough details to construct a comprehensive and accurate response.
Here’s a summary of the key details I’ve gathered:
- Model: 9786-110
- Function: Analog Input (AI) External Termination Panel (ETP). The “97” series denotes an ETP, and the “86” seems to be associated with analog input functions.
- Signal Type: The search results specifically mention it’s for a “Thermocouple input” with “upscale/downscale” capabilities and “16 pts.” This is a critical detail, as it defines its specialized purpose.
- Voltage: The “-110” suffix, in this context, is not a voltage for the termination panel itself but rather a part of the model number for a specific I/O module configuration. The panel itself is a passive wiring interface. However, the context of the associated modules often points to a 115 VAC or similar AC voltage environment.
- Compatible Modules: The panel is designed to work with a 16-point thermocouple input module, although the specific module number is not explicitly stated in the search results alongside the 9786-110. It is part of the Triconex v9-v11 systems.
- Special Features: The search results also mention it’s designed for “Hazardous Location (ATEX)” environments. This is a very important safety-related feature that I must highlight.
I have sufficient information to construct a detailed response for the user. I’ll summarize these findings and present them in a clear, well-structured format. I’ll describe its function, its unique features (thermocouple and hazardous location capabilities), its role in a Triconex system, and a technical specifications table. I will also be sure to explicitly state that it is a termination panel for an I/O module, not the module itself. The Triconex 9786-110 is a specialized External Termination Panel (ETP) designed for use in Triconex safety instrumented systems. It serves as a secure, pre-wired interface for a 16-point thermocouple analog input module, particularly for applications in hazardous environments.
Triconex 9786-110 Analog Input Termination Panel
Brief Product Description
The Triconex 9786-110 is an Analog Input (AI) External Termination Panel. It’s specifically engineered to connect field wiring from a 16-point thermocouple input module to the Triconex controller. A key feature of this panel is its design for hazardous locations, often meeting standards like ATEX, ensuring the integrity and safety of the system in potentially explosive atmospheres.
- Product Type: Analog Input External Termination Panel (ETP)
- Compatible Module: 16-point Thermocouple Input Module
- Key Feature: Designed for use in hazardous environments, with support for thermocouple signals and upscale/downscale diagnostics.
Why the 9786-110 Is Essential for Your System
In safety-critical applications, a reliable and safe wiring interface is as important as the I/O modules themselves. The Triconex 9786-110 provides a robust solution for a thermocouple input module.
Its primary functions include:
- Simplified and Secure Wiring: Instead of running delicate thermocouple wires directly to the I/O module, you connect them to the ETP’s durable screw terminals. A single, pre-fabricated cable then links the panel to the Triconex module, minimizing wiring errors and protecting the sensitive electronics.
- Hazardous Location Compliance: This panel’s design and certification for hazardous locations ensure that the physical wiring infrastructure meets stringent safety standards, which is vital in industries like oil & gas, petrochemicals, and pharmaceuticals.
- Enhanced Diagnostics: The ETP provides the necessary interface for the module’s diagnostic features, such as upscale/downscale open-thermocouple detection. This allows the system to immediately detect a broken sensor wire, an essential safety function.
- Facilitates Hot-Swapping: Like other Triconex components, the ETP enables the system’s hot-swapping capability. If a thermocouple module needs to be replaced, technicians can do so without disturbing the field wiring or shutting down the entire process.
