MACO IV V VI

The MACO IV, V, and VI series comprises machine control products manufactured by Barber-Colman. This family collects the electronic boards and modules used to build and maintain MACO controllers, including CPU boards, sequence control and sequence memory cards, sequential interface cards, I/O and PA rack motherboards, and an operator keypad.

These components work together as part of a MACO control system, handling the processing, sequencing, input/output, and operator interface functions of the platform.

Products in this Series

• CPU boards — the central processing element of the control system.
• Sequence control and sequence memory boards — for control sequencing and associated memory.
• Sequential interface cards — interfacing between control and sequence functions.
• I/O and PA rack motherboards — backplane boards for input/output and rack assemblies.
• Operator keypad and board (MACO VI) — the operator input interface.

Multiple revisions of several boards are represented, sharing common Barber-Colman part numbers across the MACO IV, V, and VI generations.
