The SMART Transmitter Power Supply is an advanced solution designed for powering 2-wire SMART transmitters in hazardous environments. It provides a reliable 24 V DC supply and is capable of outputting a range of 4 mA to 20 mA.
The SMART Transmitter Power Supply represents a critical component in the realm of intrinsic safety barriers, ensuring safe and efficient power delivery to SMART transmitters in explosive atmospheres. This 1-channel isolated barrier is specifically engineered to operate with a 24 V DC supply, effectively isolating field devices from the control system while maintaining signal integrity.
Common applications include industrial automation, process control, and remote monitoring, where reliable data transmission is essential. The product supports SMART capabilities up to 40 kHz (-1dB) and is compatible with the Honeywell DE protocol, making it suitable for a variety of sensor and control applications. Additionally, the terminal design includes test points, facilitating easy access for maintenance and troubleshooting.
