TSXSAZ10: A Practical Replacement for AS-Interface Master Modules
Maintenance engineers know the drill. A legacy AS-Interface master fails, and the line goes down. You need a drop-in module that speaks the same language as your existing TSX Micro PLC rack. The Schneider Electric TSXSAZ10 fills that gap. It is an AS-Interface master module built specifically for the TSX Micro PLCs series. This unit handles up to 31 server devices on a standard AS-Interface cabling system. It also provides 4 discrete inputs and 4 discrete outputs for direct I/O management. If you are maintaining older automation cells, this module keeps your AS-i network alive without a full platform migration.
Key Technical Parameters That Matter on the Floor
AS-Interface Capacity and Addressing
The TSXSAZ10 supports 31 standard server devices. That capacity suits medium-sized setups where you need to connect sensors, actuators, and remote I/O blocks. Addressing follows the standard AS-i method. You do not need proprietary tools beyond your existing AS-i addressing device. The module uses AS-i version V1 and profile M2. This means it works with common AS-i slaves that follow the same profile.
Discrete I/O Configuration
The module offers 4 discrete inputs and 4 discrete outputs. These I/Os handle straightforward control and signaling tasks. For example, you can wire pushbuttons, limit switches, or indicator lamps directly to the module. The terminal block connects to the AS-Interface line. This design reduces wiring complexity compared to discrete point-to-point runs.
Power Supply and Environmental Ratings
The TSXSAZ10 draws power from the host platform. You do not need a separate external power supply for the module itself. That simplifies installation and reduces cabinet space. The IP20 rating means the module suits controlled environments. Keep it away from direct dust and moisture exposure. Operating temperature ranges from 0 to 60 degrees Celsius. Storage temperature extends from -25 to 70 degrees Celsius. Relative humidity can range from 5% to 95%, as long as conditions remain non-condensing.
Where the TSXSAZ10 Fits in Your Operation
Replacing a Failed AS-i Master in a Packaging Line
A packaging line often uses AS-Interface to connect photoeyes, solenoids, and motor starters. When the original master fails, production stops. The TSXSAZ10 restores communication to up to 31 devices. Its 4 discrete inputs and 4 discrete outputs handle local control signals. You can swap the module without rewiring the entire AS-i trunk. This keeps downtime short and predictable.
Upgrading a Legacy TSX Micro PLC Cell
Many older cells still run TSX Micro PLCs. These controllers remain reliable, but spare parts become scarce. The TSXSAZ10 gives you a path to extend the life of that platform. It integrates directly into the TSX Micro PLCs series. You avoid the cost and risk of a full PLC migration. Instead, you replace the failed module and continue running the same logic and I/O map.
Maintaining a Medium-Sized AS-i Network
A network with 31 devices is common in smaller assembly or material handling areas. The TSXSAZ10 manages that device count without strain. Its 4 discrete inputs and 4 discrete outputs provide enough local I/O for start/stop, fault reset, and status indication. The module’s IP20 rating fits inside a standard control cabinet. You do not need a washdown enclosure or special environmental controls.
Installation and Setup for Maintenance Teams
Mount the TSXSAZ10 in the host platform according to the TSX Micro PLC rack guidelines. Connect the AS-Interface line to the terminal block. The module takes power from the host platform, so no separate supply wiring is needed. Verify that the AS-i cabling system meets the standard requirements for your network. Set the address for each server device using your standard AS-i addressing tool. Confirm that the module recognizes all 31 devices before running production. Keep the cabinet within the 0 to 60 degrees Celsius operating range. Avoid condensing humidity above 95% relative humidity.
Reliability and Serviceability in Harsh Conditions
The TSXSAZ10 carries an IP20 rating. That means it needs a clean, dry cabinet environment. Inspect the module periodically for dust buildup and loose terminal connections. Check the AS-Interface line for damage or corrosion. Because the module draws power from the host platform, verify that the host supply remains stable. Keep spare modules on hand if your line runs continuously. The 31-device capacity and 4 discrete inputs plus 4 discrete outputs cover many medium-sized applications. This reduces the number of different spare parts you need to stock. A single TSXSAZ10 can replace a failed unit and restore your AS-i network quickly.
Compatibility and Integration Notes
The TSXSAZ10 works within the TSX Micro PLCs series. It uses the AS-Interface cabling system and follows the AS-i version V1 profile M2. The module supports standard addressing. It connects via a terminal block for the AS-Interface line. The host platform provides power. This module does not require external power supplies or special communication gateways. It integrates directly into existing AS-i networks that use standard server devices. If your system uses a different AS-i profile or version, verify compatibility before ordering.
What to Verify Before You Buy
Confirm that your host platform is part of the TSX Micro PLCs series. Check that your AS-Interface network uses standard addressing and the V1 profile. Count your server devices. The TSXSAZ10 supports up to 31 devices. Review your discrete I/O needs. The module provides 4 inputs and 4 outputs. Ensure your cabinet maintains 0 to 60 degrees Celsius and non-condensing humidity. If you need a replacement or spare, SpareTechPLC can help you verify availability. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
