AB CONTROLLOGIX PLC’S HARDWARE

CONCEPT

I/O COMPONENTS (1)

The ControlLogix controller provides a scalable controller

solution that is capable of addressing a large amount of I/O

points.

The ControlLogix controller can be placed into any slot of a

ControlLogix I/O chassis and multiple controllers can be installed

in the same chassis.

I/O COMPONENTS (2)

• Multiple controller modules on the backplane can pass

messages between one another.

I/O CHASSIS (2)

TECHNICAL SPECIFICATIONS - 1756

CHASSIS

1771 POWER SUPPLY

ControlLogix power supplies are used with the 1756 chassis to

provide 1.2V, 3.3V, 5V, and 24V DC power directly to the chassis

backplane.
