YOKOGAWA NFAI841-S50 Analog I/O Module

Description

YOKOGAWA NFAI841-S50 Analog I/O Module is a high-performance DC-powered analog input/output module with a power consumption range of 0.5W to 1.5W, 98% conversion efficiency, and low heat generation. It supports ultra-wide operating conditions, including a temperature range of -20 degrees Celsius to 85 degrees Celsius and an input voltage range of 9V to 100V, making it suitable for harsh industrial environments. The module offers configurable analog input channels, supporting 4 or 8 channels with input ranges of 0-5V, 0-10V, and 0-20mA; it also supports additional input types such as 4-20mA current, thermocouples, and RTDs. Key performance parameters include 16-bit resolution, 10ms per channel sampling speed, ±0.1% FS accuracy, and temperature drift of ≤50 ppm/C. It features input-to-system isolation of 1500V AC for enhanced signal stability and protection. Communication is enabled via shared RS-485 and RS-232 serial ports, and a built-in calibration interface allows for high signal precision when paired with calibration programs and signal sources. The module supports DIN rail or rack mounting, with dimensions of 30×120×110mm, and operates in relative humidity of 5% to 95% without condensation, with a storage temperature range of -25 degrees Celsius to 85 degrees Celsius.
