The Yokogawa SAI533-H33 is an analog output module designed for industrial process control systems.

It converts digital signals from a control system into a 4-20 mA current signal that can be used to control various field devices like valves, actuators, or recorders.

Here’s a breakdown of the key features of SAI533-H33:

• Analog Output: It outputs a continuous current signal between 4 and 20 milliamps (mA). This industry-standard signal is used to represent a proportional range of a process variable.
• Current Loop: Operates on a 4-20 mA current loop, which is a reliable and immune to noise transmission method for industrial environments.
• Dual Redundancy: The SAI533 can be configured for dual redundancy, meaning two modules can be used together for increased system reliability. If one module fails, the other can continue operation.
