A-B Allen-Bradley

1.Main Functions

1. Remote I/O network communication interface Connects local FLEX I/O cluster to PLC‑5, SLC‑500 and legacy Logix‑family controllers over Universal Remote I/O link. Supports baud‑rates: 57.6 Kbps, 115.2 Kbps, 230.4 Kbps. Executes block‑transfer‑read (BTR) and block‑transfer‑write (BTW) instructions to exchange input/output data between remote I/O rack and main processor.
2. Integrated Flexbus backplane power generation Converts external 24 VDC input into isolated 5 VDC bus power for downstream FLEX I/O terminal bases and I/O modules. Maximum Flexbus output current: 640 mA. Supports up to 8 pieces of FLEX I/O modules on one local adapter rack, mixing digital, analog and specialty I/O modulesRockwell A….
3. Distributed I/O signal data collection & forwarding Collects field input signals from attached FLEX I/O modules, transmits data to the main PLC scanner. Receives output commands from controller and distributes commands to local output modules. Realizes remote distributed signal acquisition and control without long‑distance field wiring back to central cabinet.
4. Status indication and on‑board diagnostic Equipped with front‑panel LED indicators: Adapter Active, Adapter Fault, Local Fault. Visibly reports communication link health, module failure and local I/O fault status for fast on‑site troubleshooting.More products: www.plcva.com

1. Rack addressing configuration DIP‑switch configurable remote rack address. Supports unique addressing mode or duplicate‑address mode for different system layout requirements within Remote I/O networkdocs.rs-on….
2. Pass‑through 24 VDC field power daisy‑chain Terminal terminals allow daisy‑chaining 24 VDC field power to subsequent terminal bases, simplifying field‑power wiring for the FLEX I/O station.

Important limitation: This module cannot work standalone. It must be used with FLEX I/O terminal bases, corresponding digital / analog I/O modules, and a Remote‑I/O scanner installed in main PLC chassis. It is not a standalone power supply; external 24 VDC source is still required for adapter itself.
