YOKOGAWA SAI146-H63 ANALOG INPUT MODULE TAKE OUT NO DHL SHIP

Description:

The Yokogawa SAI146-H63 Analog Input Module is used a multi-channel current input module used in Yokogawa CENTUM and ProSafe-RS control systems. It converts analog field signals (typically from transmitters) into digital data for processing by the control system. The “H63” suffix indicates HART communication capability, Yokogawa-specific cable interface, and extended environmental rating.

Applications:

The Yokogawa SAI146-H63 is used in industrial environments for acquiring analog signals from field instruments. It is commonly deployed in chemical processing, oil & gas, power generation, and manufacturing systems. The module enables real-time monitoring of variables such as pressure, flow, level, and temperature, ensuring stable and accurate process control.
