Description
Product Name: 1786-TPS/C Allen Braley Controller module
Product details:
The Allen-Bradley 1786-TPS/C is a ControlNet Coaxial T-Tap Connector. It is an essential component used in a ControlNet coaxial network architecture to physically tap into the main trunk line (the backbone cable) and provide a connection point for a ControlNet device (such as a ControlNet Scanner, Repeater, or a device with a ControlNet interface).
It allows for a simple, non-intrusive connection to the main communication cable without cutting or splicing the trunk line, maintaining the network’s integrity.
⚙️ Product Parameters (产品参数)

| Connector Type | Two female BNC connectors for the trunk cable in/out, and one straight male BNC connector for the drop cable to the device. |
| Function | Provides a tap for connecting a drop cable to the main ControlNet trunk cable. |
| Operating Temperature | Often specified around $-20$ to $70^\circ\text{C}$ (Standard industrial temperature range) |
| Relative Humidity | $5$ to $95\%$ non-condensing |
✨ Product Advantages (产品优势)
-
Network Scalability: Allows for easy and flexible expansion of the ControlNet network by adding or removing nodes without major network disruption.
-
Ease of Installation: Simple “T” connection design simplifies wiring. It allows a device to be added to the network by tapping into the existing trunk, rather than requiring the trunk cable to be broken and terminated.
-
Signal Integrity: Designed specifically for ControlNet’s high-speed, deterministic communication, ensuring proper impedance matching and minimal signal reflection when installed correctly.
-
Robust Industrial Design: Built to withstand harsh industrial environments, consistent with Allen-Bradley’s industrial hardware standards.
-
ControlNet Standard Compliance: Ensures compatibility and reliable performance within a standard ControlNet architecture.
⚠️ Precautions (注意事项)
-
Termination: The ControlNet coaxial trunk line must be properly terminated at both ends using $75\ \Omega$ terminators (e.g., Allen-Bradley 1786-RT or similar). The T-Tap itself is not a terminator.
-
Cable Specifications: Use the correct $75\ \Omega$ impedance coaxial cable (typically RG-6 Quad Shield) for both the trunk and drop lines. Using the wrong cable type will severely degrade network performance.
-
Drop Cable Length: Adhere to the specified maximum length for the drop cable (the cable from the T-Tap to the device) as defined by the ControlNet standard to prevent signal degradation and timing issues.
-
Proper Connections: Ensure all BNC connections are tight and secure to maintain network signal quality and reliability. Loose connections can introduce noise.
-
Environmental Limits: Ensure the operating environment (temperature, humidity) remains within the product’s specified limits.
🏭 Product Application (产品应用)
The 1786-TPS/C is primarily used in Industrial Automation and Control Systems where ControlNet is the chosen network for high-speed, deterministic I/O and peer-to-peer communication.
Common applications include:
-
Distributed Control Systems (DCS): Connecting ControlLogix or PLC-5 controllers to remote I/O chassis over a large plant area.
-
Machine Control: Linking multiple high-speed devices (such as motion controllers, HMIs, and VFDs) on a production line network.
-
Process Control: In industries like oil & gas, chemicals, and pharmaceuticals, for high-reliability data exchange between controllers and field devices.
-
Connecting Network Infrastructure: Used to tap into the trunk line to connect components like ControlNet repeaters or bridges.
