1785-SO036C-EN-P - April 2002
1771 chassis The PLC-5 controller requires a 1771 chassis. You can also place
local 1771 I/O modules in this same chassis.
The consistent size and mounting of the available 1771 chassis
provide a “universal” configuration for system design and
chassis-mounting configurations. Select the chassis size that best fits
your application:
requires rackless design with panel or DIN-rail mounting
requires modular, high-density I/O
1769 Compact I/O

DeviceNet, Local I/O
requires I/O with built-in power supply and network adapter
distinct functionality and reduced environmental requirements
