Schneider Electric TSXDSZ08R5 – 8‑Channel Relay Output Module for Modicon TSX Premium Racks

The Schneider Electric TSXDSZ08R5 is an 8‑point relay output module designed for Modicon TSX Premium PLC systems. From my experience, it’s the go‑to choice when you need robust, dry-contact outputs that can switch a mix of AC and DC loads without worrying about transistor compatibility. You might notice that it fits a single slot on the TSX Premium rack and brings straightforward wiring and per‑channel status LEDs that make troubleshooting faster on the plant floor.

Order Placement Process and Guarantees

• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Eight relay outputs – Dry contacts suitable for mixed AC/DC loads, typically preferred for field devices like contactors, solenoids, and small valves.
• Backplane-powered – Draws logic power from the TSX Premium rack; outputs switch your external supply without needing a separate internal module supply.
• Channel status LEDs – Quick diagnostics at the front panel; in many cases you’ll pinpoint a wiring issue in seconds.
• Isolation by relay contacts – Mechanical isolation helps when driving noisy inductive loads, typically improving resilience compared with transistor cards.
• Single-slot format – Compact footprint on TSX Premium racks, leaving room for additional I/O or comms.
• Field-proven durability – A maintenance supervisor told us the relays hold up well on frequent-switching applications when proper snubbers are used.

Technical Specifications

Related or Supporting Products

• TSXDSZ16R5 – 16‑channel relay output module; doubles the point count while keeping similar relay behavior.
• TSXDSY08T2 – 8‑channel 24 VDC transistor output; faster switching than relays for DC-only loads.
• TSX RKY racks and TSX PSY power supplies – Required base components for TSX Premium systems.
• Migration option: If upgrading to Modicon M340, the BMXDRA0805 is a comparable 8‑point relay output module (not drop‑in; requires M340 rack and wiring changes).

Installation & Maintenance

• Cabinet environment: Install in a clean, dry, ventilated control cabinet. Maintain ambient within the specified temperature range and avoid condensation.
• Rack and wiring: Mount on a TSX Premium rack. Use proper wire ferrules; segregate high‑voltage and low‑level wiring. Provide external fusing/breakers sized to the load.
• Inductive loads: Add RC snubbers (AC) or flyback diodes (DC) to protect relay contacts; this typically extends service life significantly.
• Grounding and EMC: Follow Schneider grounding practices; route cable shields to a clean ground to reduce noise coupling.
• Routine checks: Inspect terminal tightness and relay switching counts during scheduled maintenance. Replace heavily cycled relays proactively.
• Firmware/CPU: The module is passive; keep the TSX Premium CPU firmware current and document I/O mapping for easier swap‑outs.
• Safety: De‑energize all circuits before servicing. Verify zero energy and lockout/tagout when working on field wiring.

Quality & Certifications

• Certifications: CE marking; UL/CSA recognition is common for TSX Premium modules; RoHS compliance applies to later production. Exact markings appear on the product label.
• Manufacturing quality: Produced under Schneider Electric quality systems (ISO 9001 manufacturing environment).
• Warranty: 365 days replacement warranty through our supply channel.

One thing I appreciate is how forgiving these relay cards are when you’re driving a variety of legacy devices. If you’re modernizing sections of a Premium rack, this module typically lets you keep existing field circuits while planning a gradual migration.
