Product Overview

The Schneider Electric TSXDSZ08R5 is a dedicated relay output module engineered for the Modicon TSX Micro programmable logic controller series. This module facilitates the interface between low-voltage control logic and higher-voltage field devices, providing 8 independent normally open (NO) relay outputs. It is specifically designed for applications requiring galvanic isolation and the flexibility to switch both AC and DC load circuits, making it a robust solution for industrial automation tasks including motor control, solenoid actuation, and valve management.

Features

• Galvanic Isolation: Ensures electrical separation between the controller backplane and field-side power circuits, protecting sensitive CPU components.
• Flexible Switching: Supports a broad operating voltage range from 24 to 240 VAC or 24 to 48 VDC.
• Integrated Diagnostics: Features dedicated LED indicators for each channel, providing real-time visual verification of output status.
• Inductive Protection: Includes onboard RC snubber circuitry to suppress voltage spikes generated by inductive loads.
• Removable Terminals: Equipped with removable screw terminal blocks to simplify field wiring and module replacement without disconnecting individual wires.

Applications

This module is suitable for various industrial environments, including energy management, manufacturing process control, and infrastructure automation. Its relay-based design is ideal for interposing logic signals in systems where electrical isolation from the main control bus is a critical safety or operational requirement.

Technical Specifications

Installation Guidelines

• Ensure the controller power is disconnected before installing or removing the module.
• Mount the module in a location that allows for adequate airflow to maintain the specified operating temperature range.
• Use shielded cabling for field wiring to minimize electromagnetic interference (EMI) in high-noise environments.
• Verify that the total load current does not exceed the 10 A module limit to prevent thermal damage.
• Ensure that the terminal block is securely seated and screws are tightened to the appropriate torque to maintain reliable contact.

FAQ

What type of loads can the TSXDSZ08R5 switch?

The module is designed for both AC and DC loads, supporting 24-240 VAC and 24-48 VDC. It is particularly useful for switching inductive loads such as contactors, relays, and small solenoid valves.

Is this module compatible with all TSX Micro racks?

The TSXDSZ08R5 is designed specifically for the Modicon TSX Micro backplane. Please consult your system documentation to ensure your specific CPU and rack configuration support this module type.

Does the module require external power for the relays?

The module draws its internal logic power from the backplane, but the field-side load circuits must be powered by an external source appropriate for the connected devices.
