TIDA-00017 is an eight-channel digital input module front-end reference design for programmable logic controllers (PLCs). It is designed and fully tested to meet IEC61000-4 EMC and surge requirements for industrial automation systems to reduce time to market. The design serializes eight digital inputs, up to 34-volts each, minimizing the number of isolation channels and GPIO pins required of the host interface. Serialized data and control signals are galvanically isolated from the PLC using our high-speed, 4242-volt peak digital isolator technology. The design also includes an over-current protected, isolated power supply providing all necessary module voltages. Full documentation, test results, design files and necessary firmware are also available for this design.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
