Schneider TSX 17 ACC 10 | TSX 17 Bus End Adapter

The TSX 17 ACC 10 terminates the end of a TSX 17 communication bus. This small adapter plugs directly into the last module of your PLC network. It prevents signal reflections that corrupt data transmission on long cables. Consequently, your fieldbus communication remains stable and error-free.

You must install this terminator at both physical ends of the bus. The TSX 17 ACC 10 matches the characteristic impedance of the cable perfectly. It works with all TSX 17 series PLCs and expansion racks. Therefore, this adapter ensures reliable network performance for your automation system.

Technical Specifications and Termination Value

The adapter contains a precision resistor for proper line termination. This resistor matches the standard 90-ohm impedance of TSX 17 bus cables. The TSX 17 ACC 10 does not require any external power source. It functions as a completely passive electrical component for signal conditioning.

The adapter features a molded plastic housing for durability. The TSX 17 ACC 10 resists vibration and industrial contaminants effectively. It stores no energy and contains no active electronic components. Below is a complete breakdown of its technical characteristics.

Interface and Installation Process

The adapter features a 4-pin male connector for bus attachment. The inserts into the unused port of the end device. A locking mechanism secures the adapter against accidental disconnection. You can install or remove it without any special tools.

Identify the physical ends of your TSX 17 bus network first. The belongs at the last module on each end. Do not place this adapter in the middle of the bus line. Therefore, proper placement follows basic fieldbus termination rules.

Operational Benefits for Network Reliability

This bus end adapter eliminates communication errors from signal reflections. The TSX 17 ACC 10 improves data integrity for all connected devices. It also prevents network dropouts during high-speed data transmission. Maintenance teams keep spare adapters for quick troubleshooting of bus faults.
