The Yokogawa SAI143-H63 is a 16-channel analog input module designed for industrial process control applications.

It takes analog signals from field devices and converts them into digital signals for use by a control system. Here’s a closer look at its features:

• Number of Channels: 16 isolated channels, meaning each channel is electrically isolated from others to prevent interference.
• Input Type: Current input, typically designed to work with the industry standard 4-20 mA current loop. This means that field devices like pressure transmitters, temperature sensors, or flow meters can connect to the SAI143-H63 and send their analog readings as a current between 4mA (minimum) and 20mA (maximum).
• Digital Communication: The “H” in the model number signifies it has digital communication capability using the HART protocol. HART allows for remote communication with the module for configuration, diagnostics, and even calibration of some connected devices.
