Texas Instruments Introduces New Isolator for Enhanced System Safety
Dallas, Tuesday, 15 July 2025.
Texas Instruments’ ISO1212DBQ isolator ensures 24 V digital input signal isolation, addressing ground loop challenges in industrial automation and IoT, enhancing system integrity and safety.
The Role of Signal Isolation in Industrial Applications
As industrial automation technology progresses, precise signal isolation becomes increasingly critical. Texas Instruments has recognized this need by introducing the ISO1212DBQ digital input isolator, a module armed with key features such as 3,000 VRMS galvanic isolation and compatibility with IEC 61131-2 standards for a 24 V DC input. By incorporating such mechanisms, engineers can safeguard sensitive electronic components from electrical surges and noise, minimizing faults and enhancing system reliability [1].
Advanced Features and Benefits
The ISO1212DBQ distinguishes itself with a wide input voltage range from 9V to 30V DC, ensuring versatility across various industrial applications. Its dual-channel design not only aligns with European market standards but also simplifies PCB design while reducing the need for external components. Compared to traditional optocouplers, this isolator provides the advantages of lower power consumption and a longer lifespan, attributes especially valuable for preserving energy efficiency in industrial environments [1].
Application Examples in IoT and Automation
Applications in industrial automation and the Internet of Things (IoT) are particularly well-suited to benefit from the ISO1212DBQ. Within control systems and industrial devices such as Programmable Logic Controllers (PLCs), effective isolation defends against ground loops and surge impulses. By ensuring the signal integrity of high-voltage input systems, the ISO1212DBQ mitigates potential disturbances that could derail critical processes, thereby promoting uninterrupted operational workflows [1].
Design Considerations for Engineers
For engineers tasked with the design of robust industrial systems, the ISO1212DBQ presents several design simplifications. Its integrated protection mechanisms, along with built-in fault detection, allow for streamlined integration into existing systems while enhancing overall safety profiles. With such features, engineers can more easily meet stringent regulatory requirements and optimize their systems’ reliability and efficiency, ultimately leading to reduced downtime and maintenance costs [1].
