The SMART Current Driver is a 1-channel signal conditioner designed for reliable operation in industrial environments. It provides a current output compatible with loads up to 650 ohms, ensuring precise control of HART I/P devices and valve positioners.
The SMART Current Driver is a vital component in the field of process automation, particularly in hazardous areas where intrinsic safety is paramount. Designed to operate with a 24 V DC supply, this signal conditioner effectively translates sensor signals into standardized outputs, facilitating seamless communication with various field devices. Its ability to handle complex applications, such as HART I/P protocols, makes it an ideal choice for modern industrial control systems.
In addition to its robust performance specifications—including lead breakage monitoring and an accuracy of 0.1%—the device is engineered to meet safety integrity level (SIL) 2 standards according to IEC 61508. This ensures that it can be deployed in safety-critical applications without compromising operational integrity. With a compact housing width of just 12.5 mm, the SMART Current Driver is designed for easy integration into existing setups, optimizing space without sacrificing functionality.
