Product Overview
The Schneider TSXDSZ08R5 is an 8-channel relay discrete output module for the Modicon TSX Micro automation platform. It provides eight normally open relay outputs through a screw terminal block, allowing a PLC to switch AC or DC loads such as contactors, solenoid valves, lamps, relays, and other industrial actuators. Schneider specifies an output voltage range of 19–264 VAC or 10–34 VDC, with a conventional free-air thermal current of 3 A. The module has a response time below 10 ms and approximately 1.5 W power dissipation. It is intended for infrastructure, machine, and manufacturing control applications. Schneider has discontinued this reference in several markets, so maintaining an exact replacement in legacy TSX Micro systems can be important for plant uptime.

Key Features and Benefits — TSXDSZ08R5
- Eight independent relay outputs for industrial actuator control.
- Normally open contacts provide galvanic switching between PLC logic and connected loads.
- Supports both AC and low-voltage DC loads within the specified voltage range.
- 3 A conventional free-air thermal current rating.
- Less than 10 ms response time for discrete switching applications.
- Screw-terminal connections simplify field wiring and maintenance.
- Designed specifically for Modicon TSX Micro installations.
Personally, I would check the load category before selecting a replacement. The permissible switching capacity differs between resistive AC-12 and inductive AC-15/DC loads, so a simple comparison of voltage and current alone is not sufficient.

Installation and Maintenance — TSXDSZ08R5
Before replacement, verify the PLC rack position, terminal wiring, connected load type, fuse arrangement, and output voltage. The relay contacts should not be used beyond the specified electrical categories and load ratings. Schneider wiring documentation also specifies fast-blow fuse protection selected according to the connected load.
During maintenance, inspect terminal screws, relay contacts, insulation, and connector surfaces for overheating or discoloration. After installation, test each output individually under the actual load condition and verify PLC status indication and field-device response.
Product Warranty — TSXDSZ08R5
Warranty coverage depends on supplier condition and sales terms. Confirm whether the unit is new, refurbished, or surplus and request functional-test records, traceability information, and the applicable warranty period.
The Schneider TSXDSZ08R5 is a legacy Modicon TSX Micro relay-output module. Schneider currently identifies the reference as discontinued in multiple markets, with no direct replacement listed; exact-part verification is therefore important when maintaining an existing TSX Micro installation.
