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 • 96 analog input/output points • 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-wire, 3-wire, or 4-wire devices. Additional options of D-shell, knife disconnect, and fused terminal bases are also available. Adjustable keyswitch helps prevent incorrect module insertion into a pre-configured terminal base. Terminal bases can be exchanged without moving other bases in your system. If desired, connect individual power supplies to each base to isolate modules. Plug the I/O module into the terminal base to connect the I/O bus and field devices. Remove and insert modules under power. No direct wiring to the module enables you to change modules without disturbing field wiring or system power. Mix and match I/O modules. There is a wide variety of digital, analog, and specialty modules. Each FLEX I/O system contains at least one adapter, one terminal base, and one I/O module.
