Barber-Colman A-11008-1 AC Input Card Circuit Board

Barber-Colman A-11008-1 AC Input Card Circuit Board is a legacy input-interface module from Barber-Colman’s MACO control system family. Marketed as an AC Input Card, the device functions as the entry point for AC-sourced signals in Barber-Colman automation racks and presents them to the MACO controller for processing by the control logic. The A-11008 naming appears in MACO documentation and parts listings as part of the Barber-Colman AC input card lineage, with related entries in the same family such as A-11008-2 noted in catalogs and repair listings. This family designation identifies the board’s role within the I/O topology of MACO equipment, providing a dedicated circuit-board solution for accepting line- or sensor-based AC inputs and delivering signals to the controller electronics. As a circuit-board component, the A-11008-1 is commonly referenced in retrofit and maintenance contexts to preserve compatibility and system operations when input-channel modules are serviced or replaced in Barber-Colman MACO installations.
