1794 FLEX I/O Overview
FLEX I/O offers:
FLEX I/O is a Distributed I/O System that connects to several Networks
including EtherNet/IP, ControlNet and DeviceNet.
Flexible, low-cost, modular I/O for distributed applications. FLEX I/O offers all
the functions of larger, rack-based I/O without the space requirements.
Independently select the I/O, termination style, and network to meet your
application needs.
Two separate connection terminals for field power let you daisy-chain power
connections to adjacent terminal bases.
One adapter communicates with up to eight I/O modules. Allows connection to:
• 256 digital input/output points, or
• 96 analog input/output points, or
• mix of I/O to meet your needs.
Modularity of FLEX I/O system provides choice of network and ease of
expansion. The wiring terminations are done almost entirely on the terminal
base. Terminal base termination selection includes screw-clamp, spring-clamp,
and cage-clamp to wire directly to 2-, 3-, or 4-wire devices. Additional options of
D-shell, knife disconnect, and fused terminal bases are available.
Adjustable keyswitch prevents incorrect module insertion into a preconfigured
terminal base.
