ADV551 Digital Output Module Series
The ADV551-E63 is a 32-channel digital output module designed to interface control systems with field devices that require discrete ON/OFF signals. Operating on a 24 V DC system, this module provides reliable signal transmission for controlling actuators, relays, indicators, and other output devices. The E63 suffix indicates extended environmental tolerance and enhanced features such as status indication and compliance with ISA G3 environmental classifications — often required in rugged or hazardous environments.
It is commonly used in distributed control systems (DCS), such as CENTUM VP platforms, and is known for its compactness, safety features, and output versatility.
