Key Features Summary
Hot-Standby Fault Tolerance
When the primary processor fails, the backup processor can switch over within milliseconds, ensuring uninterrupted operation of the control system.
Modular Design
Supports multiple communication modules and allows flexible network configuration based on field requirements.
Compact Rack
Single-rack design compatible with 6/8/12-slot PLC chassis, saving installation space.
High Compatibility
Fully compatible with Modicon Premium and Unity Pro series CPUs and I/O modules, making upgrades or expansions in existing systems easy.
Reliable Power Supply
5 V DC input with 1880 mA operating current ensures stable performance under high load conditions.
Selection Recommendations
System Size
For systems requiring only one rack and high redundancy, the TSXH5744M is the most economical hot-standby option.
Communication Requirements
Select appropriate COM modules based on the site network environment (Ethernet, Profibus, Modbus, etc.).
Task Load
If only one master task is needed (common for simple or single-logic applications), this model is sufficient.
For multi-task parallel processing, consider a higher-spec processor.
