The SMART Transmitter Power Supply is a 1-channel isolated barrier designed for the reliable operation of SMART transmitters and current sources. It provides a 24 V DC supply and facilitates output ranging from 0/4 mA to 20 mA, ensuring compatibility with various field devices.
The SMART Transmitter Power Supply is a critical component in the field of intrinsic safety barriers, specifically engineered to enhance the operational effectiveness of 2-wire and 3-wire SMART transmitters, as well as 2-wire SMART current sources. This device ensures safe and reliable power supply in potentially hazardous environments by isolating the input and output circuits, thus preventing any hazardous energy from reaching the field devices.
Commonly used in industrial applications, the SMART Transmitter Power Supply operates efficiently with a high field voltage of 17 V DC and supports outputs that can function as either a current sink or source. With its capability to achieve up to SIL 2 compliance according to IEC 61508, this power supply is suited for applications requiring a high level of safety integrity. The inclusion of terminals with test points further facilitates maintenance and troubleshooting, making it an essential component for process automation and control systems.
