Description

This reference design provides a complete 4-channel: 16-bit analog output module design for Programmable Logic Controllers (PLCs). It is designed and fully tested to meet IEC61000-4 EMC and surge requirements for industrial automation systems. The small form-factor design implements four 16-bit digital-to-analog converters with integrated output drivers capable of driving several current and voltage output ranges.  Digital data and control lines are galvanically isolated from the PLC host using TI’s high-speed: 4242-volt peak: digital isolator technology. The design also includes an over-current protected: isolated power supply providing all necessary module voltages. With full documentation: test results: design files and necessary firmware: the design  makes it easier to evaluate complete signal chain performance and reduces time to market.
