Module de pesage Schneider Modicon Premium TSXISPY121 ISP Plus

Description

The TSXISPY121 functions as a high-precision ISP Plus weighing module developed for integration within the Modicon Premium Automation platform. This specialized hardware subassembly executes rapid industrial weight data acquisition, supporting processing rates of up to 50 measurements per second. The device features a single measurement input channel with an analogue input resolution of 20 bits, translating to an internal capacity of 1,048,857 points. Designed to supply stabilized power directly to connected sensors, it outputs a constant 10 V DC sensor power supply to drive external field components.

For localized process adjustments, the hardware incorporates discrete reflex outputs with a rapid response time of 1 ms, handling positive switching states up to 500 mA at 24 V DC. Communication infrastructure is facilitated by an unisolated RS485 serial link operating at a transmission rate of 9.6 kbit/s, enabling dedicated connection paths directly to a Magelis weight indicator. This architecture makes the module highly suitable for industrial batching, filling, and dynamic crane or hopper weighing procedures across modern production lines.

Installation Guidelines

Rack Placement and Insertion

• Ensure the primary rack power supply of the Modicon Premium automation platform is switched off before inserting or extracting the hardware.
• Slide the module firmly along the structural chassis alignment paths until the rear terminal contacts mate completely into the active rack bus lines.
• Tighten the integrated faceplate screws to confirm grounding and safeguard against vibration displacement.

Cable Length and Isolation Management

• Keep the interconnection distance between the main weighing block and the dedicated remote weight indicator below the specified 3 m distance boundary to avoid transmission losses.
• When implementing field extensions for the load cell inputs, ensure the maximum shielding run does not exceed 300 m.
• Run all low-voltage analog load cell sensor cabling inside isolated trays, separated completely from primary high-current AC machinery power lines.

Compliance and Certifications

• CE 
• SDM No 97.06 

FAQ

What parameters govern the sensor compatibility for this weighing module? 

The module is designed to interface seamlessly with standard strain-gauge load cells, supporting configurations ranging from 1 to 8 parallel load cells with a nominal bridge resistance of 350 Ohm up to a maximum distance boundary of 300 m.

What are the primary electrical draws exerted by this unit on the main rack assembly? 

The device pulls electrical current across two distinct voltage rails provided by the Modicon backplane, consuming 145 mA at the 24 V rack supply line while simultaneously drawing 150 mA from the localized 5 V DC internal distribution rail.

How are the direct physical reflex output channels bound to external switching loops?

 External loops hook directly into the integrated terminal interface using a dedicated single connector screw terminal block layout, which distributes the two positive 24 V DC reflex switching points out to localized relays or indicators.
