Select Chassis 37

Select Chassis

The PLC-5 programmable controller requires a 1771 chassis to contain the

various modules. Chassis are available in sizes of 1, 2, 4, 8, 12, and 16

module slots.

The backplane provides a communication path between the I/O modules and

either the controller or the I/O adapter module.

The consistent size and mounting of the available 1771 chassis provide a

universal configuration for system design and chassis-mounting

configurations. If you anticipate that your system will expand, you may want to

purchase a larger chassis for future expansion.
