Design and Connection Features

The Schneider TSXBLY01 uses captive M3 screws for reliable wire retention. You can tighten these screws using either a slotted or Pozidriv screwdriver. A 5.08 mm pitch gives you ample space between adjacent wires. This spacing reduces the risk of accidental short circuits in crowded panels.

Wiring and Installation

This terminal block accepts solid or stranded wires from 24 to 14 AWG. You need to strip 7 mm of insulation from each wire before insertion. The screw mechanism applies even pressure to secure the conductor firmly. Consequently, vibration will not loosen your field wiring connections over time.

Compatibility and Mounting

This block mates directly with TSX Micro and Premium I/O modules. It plugs into the 20-pin male header on the front of each module. You can remove and replace the block without rewiring any field devices. Therefore, module replacement takes only seconds and requires no tools.

Electrical Ratings

Each terminal carries a maximum continuous current of 5 Amps. The block handles rated voltages up to 250 VAC or 60 VDC. You can mix different signal types across the 20 positions safely. However, follow all local electrical codes for voltage separation requirements.

Physical Construction

The PA66 housing carries a V0 flame rating for safety in industrial panels. Brass contacts with tin plating resist corrosion in humid environments. The 0.06 kg lightweight design puts minimal stress on the module connector. Therefore, you can mount this block vertically or horizontally without strain.

Practical Applications

Maintenance technicians prefer this screw terminal for its simple reusability. You can disconnect field wiring from a faulty module instantly. The same block then snaps onto a replacement module without any changes. Consequently, you reduce downtime significantly during emergency repairs.

Why Choose This Terminal Block

This original Schneider accessory guarantees perfect fit with TSX I/O modules. Aftermarket blocks often have alignment issues or lower current ratings. Therefore, choose this genuine part for reliable performance and long service life.
