- Power Consumption: 19W – energy-efficient operation.
- Weight: 0.3KG – lightweight for easy mounting.
- Dimensions: 60x90x75mm – ultra-compact footprint.
These parameters make the FX3SA-10MR-CM a practical choice for applications requiring a few control loops without unnecessary complexity.
Industry Applications
From a maintenance engineer's perspective, the FX3SA-10MR-CM excels in environments where reliability and ease of service are paramount. Common use cases include:
- Small Conveyor Systems: Control start/stop sequences and safety interlocks using the 6 inputs and 4 relay outputs.
- Packaging Machines: Manage simple pick-and-place operations or labeling processes with minimal wiring.
- HVAC Controls: Regulate fans, dampers, and pumps in building automation subsystems.
The built-in high-speed counter enables basic speed monitoring, while the anti-jitter digital filter (adjustable to 1ms) ensures stable input readings in noisy industrial settings.
Installation & Setup Guidance
Mount the FX3SA-10MR-CM on a DIN rail or directly to a panel using the provided slots. Connect the AC100-240V supply to the designated terminals, ensuring proper grounding. Wire inputs from sensors (e.g., limit switches, proximity sensors) and outputs to relays or contactors. The terminal row design simplifies field wiring and maintenance access. Always verify power polarity and load ratings before energizing.
Maintenance & Reliability
The FX3SA-10MR-CM features a battery-free design with built-in 8000-step EPROM memory, eliminating battery replacement tasks. Regular inspection of terminal connections and relay contact condition is recommended. The compact enclosure (60x90x75mm) withstands typical industrial environments, and the 19W power consumption reduces heat buildup. For long-term reliability, keep the unit clean and ensure adequate ventilation.
Compatibility & Integration
This PLC integrates seamlessly with Mitsubishi FX series expansion modules. It supports FX2NC expansion modules directly, allowing up to 60 total I/O points. Communication options include MODBUS and Ethernet via optional expansion boards, enabling data links with external serial devices. The FX3SA-10MR-CM can also connect to FX3GA/FX3G, FX3GE, FX3GC, FX3U, and FX3UC series controllers when using appropriate interface converters like FX2NC-CNV-IF.
Selection Guide & Purchasing Advice
Before ordering the FX3SA-10MR-CM, confirm your I/O count and output type requirements. This model suits applications needing 6 inputs and 4 relay outputs. For higher I/O counts, consider the FX3SA series variants with 8, 16, or 32 points. SpareTechPLC offers this model with fast shipping and technical support. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
