Description
1. Product Description
⚙️ The ABB OCAHG (492838402) is a four-channel analog output board in the ABB Satt Rack I/O family. It converts control-system commands into analog signals for compatible field devices, such as control valves, actuators, and process controllers.
🔧 The board supports selectable 0–10 V and 0–20 mA / 4–20 mA output signals, with an 8-bit resolution. Its analog circuitry is isolated from the digital control logic, while the four analog output channels are not galvanically isolated from one another. Verify the signal configuration and system compatibility before installation.
