Is Your Control System Ready for the Next Level of Automation?
Many plant engineers face the same challenge: their existing controllers cannot handle growing I/O counts, faster cycle times, and networked data exchange at the same time. The Schneider Electric TSXP573623AM micro PLC answers that challenge directly. It combines integrated Ethernet TCP/IP connectivity with a non-isolated serial link, giving you a compact controller that scales from simple machines to complex process lines.
This unit belongs to the TSX Micro PLCs product line. It ships with an EAN of 3595863914634 and weighs just 1.00 lbs (0.45 kg).
Key Parameters That Drive Real Performance
Processing Speed and Program Structure
The TSXP573623AM executes Boolean instructions in 0.12 µs without a PCMCIA card. It processes 6.57 Kinst/ms with 100% Boolean logic when no PCMCIA card is installed, and 4.49 Kinst/ms with a PCMCIA card. The application structure supports one master task, one fast task, and up to 64 event tasks. This means time-critical events get handled without slowing down the main program.
Memory and Expansion
Internal RAM provides 64 Kwords for program and data. With a PCMCIA card installed, the controller can use 80 Kwords of internal RAM. Two PCMCIA slots accept a memory extension card and a communication card or a 384 Kwords program memory extension card. Additional data storage can reach 2688 Kwords when needed.
I/O and Rack Capacity
The processor handles 1024 discrete I/O and 128 analogue I/O channels. It supports up to 16 racks, so you can distribute I/O across a large machine footprint. For process control, the unit manages 15 channels up to 45 simple loops.
Communication and Networking
Integrated Ethernet TCP/IP runs through an RJ45 port at 10/100 Mbit/s. A non-isolated serial link uses two female mini DIN connectors at 19.2 or 115 kbit/s. The communication module processor capacity allows 2 fieldbus modules (1 if CANopen is used) and 8 AS-Interface bus modules.
Where the TSXP573623AM Fits Best
Replacement and Upgrade Path
Plants running older TSX Micro systems often need a drop-in controller that speaks Ethernet natively. This model fits that role. When an aging CPU cannot support 16 racks or 1024 discrete I/O, the TSXP573623AM restores headroom without a full cabinet redesign.
Process Control Loops
With 15 process control channels and support for up to 45 simple loops, this PLC suits temperature, flow, and pressure control in food processing, water treatment, and chemical dosing. The 64 event tasks let you trigger fast responses to alarms or interlocks.
Discrete Manufacturing
Packaging, assembly, and material handling lines benefit from the 1024 discrete I/O capacity and the fast Boolean execution time. The front-panel LED display block gives operators immediate status feedback.
Installation and Setup Guidance
Mount the unit inside a control cabinet that meets your site’s environmental requirements. Keep the RJ45 Ethernet cable separated from high-voltage power wiring to reduce noise on the 10/100 Mbit/s link. Route the two female mini DIN serial connectors to your programming terminal or HMI using shielded cable. The RESET button causes a cold start of the PLC when pressed, so protect it from accidental contact during normal operation. Verify rack addressing and I/O module placement before power-up.
Maintenance and Reliability
Inspect the cabinet fan and filter regularly to prevent overheating. Check LED indicators on the front panel during routine rounds; a change in LED behavior often signals a fault before production stops. Verify that PCMCIA cards sit firmly in their slots. Keep spare PCMCIA memory and communication cards on hand to reduce downtime. Because this controller supports up to 16 racks, label each rack clearly to speed up fault tracing.
Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Compatibility and Integration
This PLC integrates with Ethernet TCP/IP networks through its RJ45 port. The non-isolated serial link connects to devices that use 19.2 or 115 kbit/s rates. The communication module capacity supports 2 fieldbus modules (1 if CANopen is used) and 8 AS-Interface bus modules, so you can tie the controller into broader plant networks.
Selection Checklist Before You Buy
Confirm your required I/O count against the 1024 discrete and 128 analogue channel limits. Check whether your application needs the 384 Kwords program memory extension card or the 2688 Kwords data storage option. Decide if you need one or two PCMCIA cards. Verify that your network uses Ethernet TCP/IP or the serial link rates listed above. SpareTechPLC supplies this model and can confirm availability.
