AAI543-H50 / A4S00 | Yokogawa | Isolated Analog Output Module | 16-Channel

Product Description

The AAI543-H50 / A4S00 analog output module from Yokogawa is engineered for distributed control systems requiring precise and reliable signal transmission. With 16 isolated output channels, it delivers 4–20 mA analog signals with high accuracy and stability. The H50 suffix indicates HART protocol support and redundancy capability, while the A4S00 option adds a pressure clamp terminal block (Model: ATA4S-00) for secure and flexible wiring.
