The SMART Transmitter Power Supply provides reliable and safe power for 2-wire SMART transmitters and current sources in hazardous environments. It operates on a 24 V DC supply and offers dual output capabilities for effective signal management.
The SMART Transmitter Power Supply is an essential component in the realm of intrinsic safety barriers, designed to ensure safe operation in hazardous areas. This 2-channel isolated barrier is engineered to supply power to 2-wire SMART transmitters and current sources, effectively isolating the field devices from the control system. This functionality is crucial in environments where safety and efficiency are paramount.
One of the key features of this product is its ability to function as a signal splitter, allowing one input to provide two outputs. This dual output configuration supports a current range of 4 mA to 20 mA, making it suitable for various industrial applications. Additionally, the device incorporates line fault detection (LFD) and meets safety requirements up to SIL 2 according to IEC 61508 standards, ensuring compliance with stringent safety regulations.
