Overview
The Yokogawa SAI533-H33 Analog Output Module is designed to provide accurate and reliable analog signals to field devices such as valves, actuators, and regulators. With 8 galvanically isolated output channels, it ensures safe, interference-free operation in complex industrial environments, making it suitable for safety-critical applications.
The module supports rated output ranges of 1.25–23 mA, with a standard 4–20 mA range, offering ±48 µA accuracy and ±16 µA/10°C temperature drift. Its 40 ms data update frequency enables responsive control, while 1.5 kV AC isolation and compatibility with resistive loads of 230–600 Ω ensure reliability under harsh conditions.
Compact in design and compatible with Yokogawa’s ProSafe-RS platform, the SAI533-H33 is ideal for industries such as oil & gas, chemical processing, and power generation.
