ABB AO801 Analog Output Module 8 Channel 4-20mA

Product Overview

The ABB AO801 is an 8-channel analog output module. It belongs to the S800L I/O series. This module provides unipolar single-ended signals. It supports 0 to 20 mA and 4 to 20 mA ranges. The resolution is 12 bits. The module has groupwise isolation from ground. It offers high accuracy with an error of only 0.1 percent. The temperature drift is typical 30 ppm per degree Celsius. This makes it stable in changing conditions. The AO801 features a short circuit proof output. It can drive loads up to 850 ohms. The update cycle time is just 1 ms. This ensures fast response for control loops.

Application Scenarios

This module is perfect for process control systems. It works well in chemical plants. It is also used in oil and gas facilities. The AO801 can control valves and actuators. It is suitable for driving indicators and recorders. The module handles analog signals for motors. It integrates easily into ABB control systems. The device meets marine standards like ABS and DNV. It also has ATEX Zone 2 approval. This makes it safe for hazardous areas. You can use it in power generation. It also fits in water treatment plants.
