The TIDA-010988 is an eight-channel analog input module with 2-terminal inputs for industrial automation applications. Each channel supports software-selectable voltage range of 0V to 10V and ±10V, as well as current range of 4mA to 20mA, ±20mA. The design implements a high-density isolated analog input module powered from either a single 24V field supply or 5V USB. By using the ADS125H18 chip-select forwarding feature, the design implements a shared SPI architecture that reduces the required digital isolation channel count. The system is designed to achieve over temperature system absolute accuracy error better than 0.1% for voltage input and 0.2% for current input.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
