Schneider TSXSAY1000C Coated AS-Interface Master Module

Product Overview

The TSXSAY1000C is a specialized AS-Interface (AS-i) Master Module designed for the Schneider Electric Modicon Premium automation platform. This "C" version is characterized by its conformal coating (Humiseal 1A33), which provides superior protection against moisture, dust, and chemical contaminants, making it ideal for harsh industrial environments. Operating as a bridge between the Modicon Premium rack and the AS-i cabling system, the TSXSAY1000C supports V2 standard and extended addressing, allowing for a highly flexible and scalable network of actuators and sensors. By simplifying field wiring into a single two-wire cable for both power and data, this module significantly reduces installation costs and improves diagnostic capabilities in complex automated systems such as bottling plants, conveyor networks, and specialized machinery.

Technical Configuration

The TSXSAY1000C is engineered for high-density networking and robust environmental performance:

• AS-i V2 Capabilities: Supports the M2E profile, enabling the management of standard slaves as well as extended addressing slaves.

• Slave Capacity:

• Standard Addressing: Up to 31 slaves (Analog I/O, Discrete 4I/4O, or Safety interfaces).

• Extended Addressing: Up to 62 slaves (Discrete 4I/3O), significantly increasing the network's point density.

• Conformal Coating: Treated with Humiseal 1A33, ensuring long-term reliability in corrosive atmospheres or high-humidity zones.

• Host Integration: Powered directly via the Modicon Premium backplane (450 mA at 5 V DC), eliminating the need for external module power supplies.

• Interface Diversity: Capable of interfacing with a variety of modules including safety-rated interfaces and analog I/O units.

• Communication Physical Layer: Features a 3-way male SUB-D connector for secure and reliable connection to the AS-i bus.

Technical Specifications

Technical FAQs

How many modules can I install in a TSX57310 processor rack?

For the TSX573 series, the system supports up to 8 AS-i master modules per base controller. This allows for massive decentralized I/O scaling within a single PLC project.

What is the benefit of the "C" designation in TSXSAY1000C?

The "C" stands for Coated. While the standard TSXSAY1000 is suitable for clean industrial environments, the TSXSAY1000C is designed for "Harsh" environments where airborne pollutants or humidity could otherwise cause short circuits or corrosion on the PCB.

Does the module provide power to the AS-i bus?

No. While the module takes its own logic power (450 mA) from the Premium rack, the AS-i bus itself requires a dedicated AS-i Power Supply (usually 30 V DC with integrated data decoupling) to power the field sensors and actuators.

Engineering & Installation Guide

Addressing and Commissioning

When using extended addressing (V2), ensure that your slaves are also V2 compliant. Extended addressing divides the standard 31 addresses into "A" and "B" banks, allowing for 62 total devices. Use the local signaling display unit on the front of the TSXSAY1000C to identify address conflicts or bus faults during the initial power-up.

Wiring and SUB-D Connection

The 3-way SUB-D connector is the primary gateway to the AS-i bus. Use high-quality, shielded AS-i yellow flat cable for the field run. Ensure that the total cable length does not exceed 100 meters without the use of AS-i repeaters. Even with the Humiseal 1A33 coating, ensure the SUB-D connector is firmly tightened to maintain a gas-tight seal at the connection point.

Environmental Protection

The IP20 rating means the module must be installed in an enclosure. Because this is the coated version, it is specifically intended for cabinets located in "Class 3C2" or similar environments. Maintain a vertical mounting orientation to facilitate natural convection, as the module consumes nearly 2.25 Watts of power from the backplane, which must be dissipated to stay within the 0…60 °C operating range.
