Advantech ADAM-4024 | 4-Channel Analog Output Module

Advantech ADAM-4024 | 4-Channel Analog Output Module

The ADAM-4024 is built for industrial control systems that need stable, repeatable analog outputs in a distributed architecture. With four differential analog output channels, it supports common control standards including 0 to 20 mA, 4 to 20 mA, and plus or minus 10 V, allowing direct interface to valves, actuators, drives, and signal converters. The module communicates using Modbus RTU and ASCII command protocols, making it easy to integrate into PLC, SCADA, and edge gateway environments where RS 485 networks are used for reliable long distance field communication.

For demanding installations, the ADAM-4024 combines signal performance with industrial protection. It includes 3,000 VDC isolation for analog outputs and also provides four isolated digital input channels for auxiliary status monitoring. A watchdog timer system rated at 1.6 seconds supports system and communication resilience, while programmable output slope control helps reduce process shock by limiting how quickly outputs change. With wide unregulated 10 to 30 VDC power input and industrial environmental ratings, the ADAM-4024 is a strong fit for remote panels and harsh plant floor locations.
