The SMART Transmitter Power Supply is a versatile 2-channel isolated barrier designed for powering and interfacing with SMART transmitters and current sources. It operates on a 24 V DC supply and is suitable for various industrial applications.
The SMART Transmitter Power Supply is engineered to provide reliable power and signal isolation for SMART 2-wire and 3-wire transmitters, as well as 2-wire SMART current sources. This device is particularly effective in environments requiring intrinsic safety barriers, ensuring that equipment operates safely in potentially hazardous areas. It delivers an output current range of 0/4 mA to 20 mA, making it suitable for a wide array of industrial measurement and control applications.
Designed with a focus on safety and compliance, the power supply is capable of achieving up to SIL 2 in accordance with IEC 61508 standards. This makes it an ideal solution for industries where safety and functionality are paramount, including process automation, chemical processing, and oil and gas sectors. Its bus-powered operation minimizes installation complexity and enhances system efficiency.
