The SMART Transmitter Power Supply is an advanced 1-channel isolated barrier designed for reliable operation in hazardous environments. It supports both 2-wire and 3-wire SMART transmitters as well as 2-wire SMART current sources, providing a dual output of 0/4 mA to 20 mA.
The SMART Transmitter Power Supply is engineered to facilitate the integration of SMART transmitters in industrial applications, ensuring safe and effective communication in hazardous areas. This product is built to provide a 24 V DC power supply through its Power Rail, supporting both 2-wire and 3-wire configurations. The design incorporates a signal splitter that allows for one input to be distributed across two outputs, enhancing the versatility and functionality of the system.
With a high field voltage rating of 17.6 V DC and compliance with SIL 3 standards according to IEC 61508, this power supply is suitable for use in safety-critical applications. The terminal blocks equipped with test sockets enable convenient testing and maintenance, ensuring optimal performance in various industrial settings. Common applications include process automation, control systems, and instrumentation where reliable intrinsic safety barriers are essential for operational integrity.
