Schneider TSXP57303AM PROCESSOR MODULE
Overview
The TSXP57303AM is a high-performance double-format PL7 processor designed for the Modicon Premium Automation platform, developed by Schneider Electric (document release date: Feb 25, 2021). As the core processing unit of the Modicon Premium system, it integrates powerful computing capabilities, flexible I/O expansion, and diverse communication interfaces, tailored for medium to large-scale industrial automation applications requiring complex logic control, process regulation, and multi-network integration.
Its robust I/O processing capacity (1024 discrete I/O + 128 analog I/O) and support for up to 45 simple loops make it suitable for process control scenarios such as manufacturing assembly lines, chemical processing, and energy management systems. The flexible rack and slot configuration (up to 16 racks, 128 slots) allows users to scale the system according to application needs, while compatibility with multiple bus modules (AS-Interface, CANopen, fieldbus) enables seamless integration with various industrial networks, facilitating data exchange between the controller and distributed field devices.
The modular memory design (expandable via PCMCIA card) balances cost and performance, meeting the storage requirements of large-scale programs and high-volume data. Fast instruction execution speeds (down to 0.12 µs for Boolean operations) ensure real-time responsiveness to control tasks, critical for time-sensitive industrial processes. The multi-tasking structure (master/fast/event tasks) supports parallel processing of multiple control logic, optimizing system efficiency and flexibility.
Practical design features enhance usability and maintainability: the LED indicator set provides clear real-time status feedback (operation, faults, communication activity), simplifying on-site troubleshooting; the double-module format fits standard Modicon Premium racks, ensuring easy installation and replacement; compliance with multiple international standards and certifications (UL 508, CSA, IEC) enables deployment across global industrial environments, including hazardous Class I Division 2 locations.
Though discontinued and replaced by the M580 series processor, the TSXP57303AM remains a reliable component for maintaining and upgrading existing Modicon Premium systems. Its 18-month warranty and proven performance ensure stable operation for legacy installations, while clear substitution information helps users plan long-term system upgrades. The product’s environmental resilience and compliance with sustainability regulations (RoHS implied via industry standards) align with modern industrial requirements, supporting reliable operation in harsh conditions while minimizing environmental impact.
In summary, the TSXP57303AM combines powerful processing, flexible expansion, and robust reliability, serving as a core control component for Modicon Premium-based automation systems. It effectively meets the demands of complex industrial control applications, providing a stable and efficient solution for logic control, process regulation, and multi-network integration—even as a legacy product, it continues to deliver value for existing system users.
Specifications
The TSXP57303AM is a double-format PL7 processor belonging to the Modicon Premium Automation platform, with a commercial status of being discontinued on 02 December 2020 and set to reach end-of-service on 31 December 2026. It is a non-stock product not normally stocked in distribution facilities and subject to restricted sales for services, replaced by the BMEP583020 M580 Level 3 distributed processor module (substitution date: 31 December 2018).
In terms of software compatibility, it supports PL7 Junior/Pro software. For system expansion, it can handle 16 racks of 4/6/8 slots or 8 racks of 12 slots, with a maximum slot capacity of 128 (64/96/128 based on configuration). The I/O processing capacity includes 1024 discrete I/O points and 128 analog I/O points, along with 32 application-specific channels and 15 process control channels (supporting up to 45 simple loops).
Communication capabilities feature a non-isolated serial link (2 female mini DIN connectors) with a transmission rate of 19.2/115 kbit/s. It can accommodate 2 fieldbus modules (1 if CANopen is used), 8 AS-Interface bus modules, 1 CANopen module, and 3 network modules.
For memory, it has internal RAM with 80 Kwords of data (with PCMCIA card) or 64 Kwords of program and data (without PCMCIA card); the PCMCIA card provides 2688 Kwords of additional data storage and 384 Kwords of program storage. The maximum size of object areas includes 16384 internal bits (%Mi), 30.5 internal data words (%MWi), and 32 internal constant words (%KWi).
In terms of operational performance, the application structure supports 1 master task, 64 event tasks, and 1 fast task. Execution time per instruction is 2.6 µs for floating points (with PCMCIA card) and 0.12 µs for Boolean operations (without PCMCIA card). The number of instructions per ms ranges from 3.08 Kinst/ms (65% Boolean + 35% fixed arithmetic, with PCMCIA card) to 6.57 Kinst/ms (100% Boolean, without PCMCIA card). System overhead is 0.29 ms for the fast task and 1.15 ms for the master task.
Physical and electrical specifications include CE marking, local signalling via 4 LEDs (green RUN for processor operation, red I/O for I/O module/configuration faults, red ERR for processor/system faults, yellow TER for terminal port activity), a current consumption of 1000 mA at 5 V DC, a double module format, and a net weight of 1.15 lb (US) (0.52 kg) with an IP20 protection degree and pollution degree 2.
Environmental resilience covers an operating ambient temperature of 32–140 °F (0–60 °C), storage temperature of -13–158 °F (-25–70 °C), operating relative humidity of 10–95% (non-condensing), storage relative humidity of 5–95% (non-condensing), and operating altitude of 0–6561.68 ft (0–2000 m). It complies with standards such as CSA C22.2 No 213 (Class I Division 2 Groups A-D), IEC 61131-2, UL 508, and multiple EU directives, holding certifications from RMRS, GL, BV, LR, ABS, DNV, and RINA.
