Loop-powered 4-mA to 20-mA transmitter EMC and EMI-tested reference design
Description
This CerTIfied Reference Design is a low cost system that implements a 12-bit loop-powered: or 2-wire: transmitter using the DAC7311: OPA317: and TL431B. The design includes a protection circuit that provides immunity to the IEC61000-4 test suite. The design also includes a circuit to rectify a reverse polarity supply voltage. The protection circuit and rectifier do not negatively affect the current output performance: resulting in This design is well suited for industrial automation and process conrol applications requiring a low-cost solution for 2-wire data transmission.
