Description
TOSHIBA SN321 Industrial Control Module
1. Product Description
The TOSHIBA SN321 is a high-performance industrial control module designed for precision automation and manufacturing systems. Engineered for reliability in harsh environments, the SN321 offers a wide input voltage range (200–240 VAC) and stable output (12–24 VDC, 5 A), making it ideal for powering sensors, actuators, and control systems. Its compact 150 mm × 100 mm × 50 mm design and IP65 protection rating ensure resistance to dust, water, and vibrations, while compliance with CE, UL, and ROHS standards guarantees global applicability. The module supports 50/60 Hz systems and operates across a temperature range of -20°C to +70°C, making it suitable for indoor and outdoor industrial settings.

3. Advantages and Features
- Robust Environmental Performance: IP65 rating and wide temperature range enable operation in challenging conditions (e.g., factories, outdoor installations).
- Flexible Power Management: Wide input voltage range reduces compatibility issues with diverse power grids.
- Compact Design: Space-saving dimensions (150 × 100 × 50 mm) simplify integration into tight control panels.
- Reliability: 99.5% uptime in 24/7 industrial operations (field-tested in automotive assembly lines).
4. Application Areas and Use Cases
- Manufacturing: Controls robotics and conveyor systems in automotive and electronics production.
- Energy: Manages power distribution in solar/wind energy installations.
- Transportation: Monitors rail and metro systems for real-time diagnostics.
Case Study: A German automotive plant deployed 200 SN321 modules to control robotic arms. Over 3 years, downtime due to voltage fluctuations dropped by 75%, saving €800,000 in maintenance costs.
5. Competitive Comparison
Compared to similar industrial control modules:
- Protection: IP65 vs. standard IP54 (better dust/water resistance).
- Voltage Range: 200–240 VAC (wider than 180–220 VAC competitors).
- Cost-Efficiency: 15% lower total cost of ownership over 10 years (due to durable design and minimal maintenance).

6. Selection Recommendations
- Voltage Requirements: Ensure compatibility with 200–240 VAC systems; use step-down converters for 110 VAC environments.
- Environmental Conditions: Opt for SN321 (IP65) for outdoor/harsh settings; choose IP20 models (e.g., TOSHIBA MC series) for clean rooms.
- Space Constraints: Leverage the compact design for modular setups; pair with DIN-rail adapters for quick installation.
- Budget: SN321 offers premium performance at a mid-range price point (20% cheaper than comparable UL-listed modules).
7. Precautions
-
Installation: Ground the module using a 6 AWG wire; secure connections to prevent vibration damage.
-
Temperature Management: Maintain airflow; avoid exceeding 70°C (use heat sinks in enclosed spaces).
-
Maintenance: Inspect terminals annually for corrosion; replace after 10 years or if physical damage is detected.
-
System Integration: Pair with TOSHIBA’s FA2100 industrial computers for centralized control in complex automation networks.
