MACO III IIIB

The MACO III and IIIB series comprises industrial control cards and boards manufactured by Barber-Colman for the MACO family of process control systems. These modular components handle signal input and output functions within the controller rack.

The series includes AC and DC input cards that process analog voltage or current signals from field devices, along with AC and DC output boards that drive control signals to connected equipment. Many of these cards are compatible across multiple MACO controller generations, including the MACO III, IIIB, IV, V, and VI, as well as EDAC configurations.

Typical Applications

Products in this series are commonly used in paper mill applications, where they interface with sensors, transmitters, and actuators to support process control and automation.

Products in This Series

• AC and DC input cards that condition field signals for the MACO controller
