TSXBLY01 Screw-Type Terminal Block | Schneider Modicon

Schneider Electric TSXBLY01 Modicon Premium Screw Connection Terminal Block — 20-Way, Analog/Discrete I/O

The TSXBLY01 is a 20-way screw connection terminal block for Schneider Electric's Modicon Premium automation platform. It provides secure field wiring connections for Premium series analog and discrete I/O modules, featuring 20 screw terminals for reliable signal termination in industrial control cabinets. Each I/O module with screw terminal block connections requires a separately ordered TSXBLY01.

Installation Guide

1. Install the Premium I/O module into the TSX Premium rack slot.
2. Attach the TSXBLY01 terminal block to the front of the I/O module (align connectors and press firmly until seated).
3. Wire field devices (sensors, actuators, transmitters) to the 20 screw terminals using appropriate gauge wire (typically #14–#22 AWG).
4. Torque screws to Schneider Electric specification (typically 0.5–0.8 N·m for screw terminals).
5. Verify all connections are secure and properly labeled.
6. Power on and verify I/O module status via PL7 Pro or Unity Pro diagnostics.

FAQ

Q: Is TSXBLY01 a PLC battery or a terminal block?
A: Terminal block. TSXBLY01 is a 20-way screw connection terminal block for Modicon Premium I/O modules. It is not a battery. Some third-party sources may confuse it with battery products due to similar naming conventions.

Q: Does TSXBLY01 come with the I/O module?
A: No. The TSXBLY01 terminal block must be ordered separately for each I/O module that requires screw terminal connections.

Q: What is the difference between TSXBLY01 and TSXBLK4?
A: TSXBLY01 is a 20-way screw terminal block for analog/discrete I/O modules. TSXBLK4 is a different terminal block configuration (typically 40-way or specialized for specific module types).

Q: Is TSXBLY01 still available?
A: Limited availability. TSXBLY01 was discontinued on 23 March 2022. Standard service (repair, spare parts) continues until 31 December 2027. Verify stock with your supplier before ordering.

Q: Can I use TSXBLY01 with M340 or M580?
A: No. TSXBLY01 is designed for Modicon Premium I/O modules. M340/M580 use different terminal block systems (BMXFTB series).

Q: What wire gauge is recommended?
A: Typically #14–#22 AWG (0.5–2.5 mm²) depending on the current rating of the specific I/O module. Refer to the I/O module datasheet for exact wire gauge requirements.

Selection Tips

• Premium analog/discrete I/O, 20-way screw terminal: TSXBLY01 (order separately for each module)
• Premium I/O, alternative terminal block: TSXBLK4 (verify compatibility with specific module)
• M340/M580 I/O terminal blocks: BMXFTB2010 (screw), BMXFTB2000 (cage), BMXFTB2020 (spring)
• Always verify: I/O module model number and required terminal block type before ordering
• Order spare terminal blocks for maintenance and module replacement
