Product Overview
The Mitsubishi FX3G-24MT/ES-A is a compact and powerful base unit from the FX3G series within the MELSEC-F SERIES. Designed for small to medium-scale automation tasks, this PLC integrates 14 digital inputs (DC 24V) and 10 transistor outputs with sink logic. Its AC power supply (100-240 V) and 32K steps program memory stored in EEPROM make it a reliable choice for demanding environments.
Technical Specifications Breakdown
- Power Supply: AC 100-240 V, ensuring global compatibility.
- Program Memory: 32K steps stored in EEPROM for non-volatile retention.
- Digital I/O: 14 inputs (DC 24V) and 10 transistor outputs (sink).
- Cycle Time: LD instruction at 210 ns and MOV at 500 ns for fast processing.
- Power Consumption: 32 W, suitable for energy-conscious designs.
- Environmental Range: Operates from 0 °C to 55 °C with IP10 protection.
- Dimensions: 90 mm (W) x 90 mm (H) x 86 mm (D), weight 0.55 kg.
Industry Applications
The FX3G-24MT/ES-A excels in applications like packaging machines, conveyor control, and simple assembly lines. Its 14 inputs handle sensor feedback while the 10 transistor outputs drive actuators directly. With expandability up to 128 local I/O points (256 with remote), it scales with your needs.
Installation & Setup Guidance
Mount the unit on a DIN rail or panel using the 90 mm width footprint. Connect the AC power supply (100-240 V) to the designated terminals. Wire DC 24V sensors to the 14 input points and sink-type loads to the 10 transistor outputs. Use the USB or RS-422 port for programming via GX Works2 or similar software. Ensure ambient temperature stays within 0 °C to 55 °C and avoid dust buildup (IP10).
Maintenance & Reliability
Periodically inspect the unit for dust accumulation and verify that the ambient temperature remains within the 0 °C to 55 °C range. The buffer battery is optional, so if latched memory retention is critical, install the battery. The EEPROM program memory retains data without battery backup. Check all connections annually to prevent loose wiring.
Compatibility & Integration
The FX3G-24MT/ES-A integrates seamlessly with other MELSEC-F SERIES expansion modules. It features one USB port and one RS-422 port for communication with HMIs, drives, or programming tools. The unit supports up to 256 total I/O points when combining local and remote modules.
Selection Guide & Purchasing Advice
Before purchasing, verify that your application requires 14 DC inputs and 10 transistor sink outputs. Confirm the AC power supply range (100-240 V) matches your facility. For expanded I/O needs, order additional FX3G expansion modules. SpareTechPLC offers this unit with fast shipping and expert support to ensure you get the right part.
