The SMART Current Driver is a 1-channel isolated barrier designed to operate with a 24 V DC supply, capable of driving current outputs up to 650 Ohm loads. It supports HART communication for integration with I/P converters and valve positioners, ensuring precise control in industrial applications.
The SMART Current Driver is a key component in the Pepperl+Fuchs family of intrinsic safety barriers, which are essential for safely transmitting signals in hazardous environments. These barriers provide isolation between field devices and control systems, ensuring that any potential faults do not propagate into the safe area. With its compact housing width of 12.5 mm, the SMART Current Driver is ideal for space-constrained installations in various industrial settings.
This product is commonly used in applications requiring precise current control, such as in process automation where valve positioners and I/P converters are prevalent. It features lead breakage monitoring to enhance reliability and accuracy, achieving an impressive accuracy rating of 0.1%. Additionally, the device meets the requirements for up to SIL 2 compliance according to IEC 61508, making it suitable for safety-critical applications where operational integrity is paramount.
