Description
Product Overview
The Schneider Electric TSXDSZ08R5 is a specialized relay output module designed for integration within the Modicon TSX Micro programmable logic controller architecture. This unit provides 8 discrete, normally open (NO) relay outputs, enabling the control of high-load field devices directly from the PLC backplane. It is engineered for industrial environments where galvanic isolation and the ability to switch varying voltage levels are critical for maintaining system integrity and protecting sensitive processor circuitry.
Features
- Eight independent, normally open (NO) mechanical relay outputs.
- Galvanic isolation between the internal logic bus and field-side contacts for enhanced safety.
- Integrated RC snubber circuits to suppress voltage spikes during reactive load switching.
- LED status indicators for each channel to verify output state and facilitate rapid field diagnostics.
- Designed for operation across a broad range of AC and DC voltage applications.
- Removable screw terminal block for efficient wiring and maintenance.
Applications
This module is suitable for various industrial automation tasks, including motor starter control, solenoid valve actuation, and interposing logic for high-voltage circuits. It is commonly deployed in sectors such as automated manufacturing, water treatment, and HVAC control systems where reliable, isolated discrete switching is required.

Installation Guidelines
- Ensure the PLC rack is powered down before installing or removing the module to prevent electrical damage.
- Mount the module securely into the designated TSX Micro rack slot, ensuring proper alignment with the backplane connector.
- Use shielded cabling for field wiring to minimize electromagnetic interference (EMI) in high-noise industrial environments.
- Verify that the total load current across all channels does not exceed the 10 A module limit.
- Maintain proper ventilation within the control cabinet to keep ambient temperatures within the specified 0 to 60 deg C range.
- Handle with standard ESD precautions to prevent damage to internal PCB components.
FAQ
Is the TSXDSZ08R5 compatible with all TSX Micro racks?
Yes, this module is specifically designed for the Modicon TSX Micro series. Please ensure your specific base configuration supports the slot requirements for this module type.
Does this module provide protection against inductive surges?
Yes, the module includes an onboard RC snubber array to mitigate counter-electromotive force spikes caused by inductive loads like relay coils or solenoids.
Can I replace the terminal block if it becomes damaged?
The TSXDSZ08R5 utilizes a removable screw terminal block, which allows for field replacement or pre-wiring without disturbing the module's connection to the backplane.
