The IS4355 represents a significant breakthrough for industrial engineers who need to bridge analog sensors with Ethernet networks. Implementing a full Modbus TCP stack is traditionally a complex, time-consuming task that requires extensive software resources. However, this chip features a native Modbus TCP stack embedded directly into the hardware. Consequently, you can bypass months of firmware development and significantly reduce your overall time-to-market.
Efficiency is at the core of the IS4355 design. This single integrated circuit manages 7 independent 4-20mA channels, providing a highly concentrated solution for dense sensor environments. Each channel accurately maps the analog current to a digital percentage within the internal Modbus registers. By consolidating seven channels into one chip, you save valuable PCB real estate and reduce the total bill of materials for your project.
Reliable communication is essential for modern industrial automation. The IS4355 acts as a dedicated server, allowing multiple clients to access sensor data over standard Ethernet infrastructure. You can easily integrate this chip with our Industrial Ethernet Gateways to build scalable monitoring systems. Because the chip handles all low-level networking protocols, your primary processor remains free to focus on high-level application logic rather than network maintenance.

Why should I choose the IS4355 over manual stack implementation? Implementing a Modbus TCP stack from scratch is error-prone and costly. The IS4355 provides a hardware-verified stack, ensuring immediate compatibility with industry-standard software and reducing your engineering expenses.
How many sensors can one IS4355 chip handle? A single IS4355 chip can manage 7 independent 4-20mA analog channels. This high density makes it perfect for concentrated sensor hubs and control panels.
Does the IS4355 support standard Modbus registers? Yes, the chip functions as a standard Modbus TCP server. The 4-20mA values are stored in accessible registers, where 4mA represents 0% and 20mA represents 100%.
Is this chip compatible with existing Ethernet infrastructure? Absolutely. The IS4355 is designed to communicate over standard Ethernet networks, making your sensor data accessible to any PLC, SCADA system, or cloud gateway on the network.
