Description
1. Product Description
⚙️ The ABB OCAHG 492838402 is a four-channel analog output board in the Satt Rack I/O family. It converts control-system commands into analog signals for industrial field devices, such as valve positioners and actuators. Documented output ranges include 0–10 V and 0–20 mA / 4–20 mA, with output selection configured by board straps.
🔧 The four output channels are not galvanically isolated from one another. Before installation, verify the signal configuration, wiring, receiving-device requirements, and compatibility with the existing SattControl system. The additional code 800164 should be checked against the product label and purchasing documentation.
