🔌 Strong Support for Industrial Automation from Toshiba​

Toshiba Electronics Europe has added four new models to its DCL34xx0B series of digital isolators, designed for industrial automation equipment. These new products offer integrated solutions for signal isolation in applications such as programmable logic controllers (PLCs), input/output interfaces, sensors, actuators, and variable frequency drives.

💡 Energy Efficiency with Magnetic Coupling​

The new digital isolators transmit digital signals across a galvanic barrier using magnetic coupling isolation technology. This enables very low power consumption, typically 0.2 milliamperes per channel. Supporting a wide supply voltage range from 2.25 V to 5.5 V, these devices can operate continuously across a broad temperature range from -40 °C to +125 °C. These features are critically important, especially in industrial environments with significant temperature fluctuations, such as switched-mode power supplies.

🛡️ Signal Integrity in Industrial Environments​

Robust protection against electrical noise and ground loops is essential to maintain data integrity in automation systems. The new isolators support data rates up to 25 megabits/second while offering a minimum isolation voltage of 3000 Vrms. To manage electrical noise caused by industrial machinery, the devices feature a minimum Common Mode Transient Immunity (CMTI) of 30 kilovolts/microsecond. This is a vital parameter for stabilizing signals in motor inverters and variable frequency drives.

⚙️ Easy Integration with Flexible Architecture​

The expansion of the DCL34xx0B series offers engineers various channel configurations in a compact SSOP16 package:

• DCL340L0B and DCL340H0B: Four forward channels (4:0 configuration).
  
• DCL342L0B and DCL342H0B: Symmetrical bidirectional data flow with two forward and two reverse channels (2:2 configuration).
  

This modular structure allows system designers to select the channel arrangement required for specific industrial communication protocols without altering the basic isolation architecture.

📊 Technical Details and Competitive Analysis​

Toshiba's new digital isolators, with their magnetic coupling technology, compete with capacitive isolation devices from companies like Texas Instruments and magnetic isolators from Analog Devices. The DCL34xx0B series' 0.2 mA power consumption per channel makes it a highly energy-efficient option for standard 25 Mbit/s industrial logic networks. The 3000 Vrms isolation rating meets industry requirements for basic galvanic isolation at common industrial control voltages and offers a direct alternative to older optocouplers, which tend to degrade over time with higher power consumption.
