AB Flex Digital I/O Module 1794-1b16

Allen-Bradley AB Flex i/o 1794-1b16

 Digital I/O Modules The FLEX I/O module plugs into the terminal base, connecting to the I/O bus and field devices. Since there is no direct wiring to the I/O module, you can remove and insert modules under power, enabling you to change modules without disturbing field wiring, other I/O modules, or system power. This eliminates costly downtime and the inefficiencies of restarting a system.
