Chapter1About the FLEX I/O SystemFLEX I/O OverviewFLEX I/O offers:AdapterTerminal baseFlexBus connectorsI/O moduleKeyswitchFlexBus connectors22 NetworkConnector24V DC field powerTerminal stripsFLEX 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 spacerequirements.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 terminalbase. 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 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 andfield devices.Remove and insert modules under power. No direct wiring to the module enables you to change modules without disturbing field wiring or systempower.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.Rockwell Automation Publication 1794-SG002H-EN-P - November 20213
Chapter 1About the FLEX I/O SystemYou can power the system with a FLEX power supply (1794-PS13 or -PS3), a 1606 switched mode power supply, or any other compatible powersource. Use the terminal block on the terminal base to wire your field devices directly. Wiring directly saves you: installation and testing time multiple, long wiring runs and external terminal blocks control cabinet panel spaceFLEX I/O provides additional savings if system problems develop. Combining your field-wiring terminations and the I/O interface into the samelocation saves you time and money by making your system easier to maintain and troubleshoot. Additionally, the full-featured FLEX I/O system letsyou, in non-hazardous location, remove, and insert modules under backplane power without disrupting your system.Your FLEX I/O system can communicate on EtherNet/IP, ControlNet, DeviceNet, and many other open networks including, but not limited, to RemoteI/O and PROFIBUS DP.Adapters and other components are available for adding to your system as your specific application requirements change.FLEX I/O XT OverviewFLEX I/O-XT modules are designated for extreme environment use.They differ from their non-XT counterparts only in operational temperature ranges and conformal coating is standard for FLEX I/O-XT products.FLEX I/O-XT modules meet or exceed the following standards: ANSI / ISA-S71.04-1985; Class G1, G2, and G3 Environments CEI IEC 6065A-4; Class 1 and 2 Environments UL 746E MIL-1-46058C to ASTM-G21; (Tropicalization and fungicide)These standards specify common emissions and classify their concentration levels in a number of industrial processes.

Chapter3Select FLEX I/O ModulesStep 2 – Select:I/O ModulesThe 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, youcan remove and insert modules under backplane power, enabling you to change modules without disturbing field wiring, other I/O modules, or FLEXbackplane power. This eliminates costly downtime and the inefficiencies of restarting a system.The choices and flexibility you have with I/O types range from digital and analog to temperature and motion control. FLEX I/O allows you to use asmany as eight terminal bases per adapter which can provide a maximum of 256 digital I/O points or 96 analog channels per adapter. You can mixand match digital and analog I/O with mounting and wiring options, supplying you with a successful distributed system solution.This flexibility gives you the following choices of I/O signal types: Digital: AC and DC voltage signals Analog: current or voltage Relay: normally open, 2 A capability Protected outputs: non-latching, latching, and with diagnostics Temperature: thermocouple or RTD Motion: high-speed counters, flow metering, and totalization Combo modules: combination of input and output capability Harsh environments: use FLEX I/O XT in harsh environmentsDigital I/O ModulesDigital I/O modules interface with field devices such as: pushbutton and limit switches on/off actuators such as motor starters, pilot lights, and annunciators Relay contactsFeaturesModules are available in different densities ranging from 8 to 32 points. Digital I/O modules cover a wide electrical range:- 120V AC: Input/Output and Isolated Input/Output, 8 and 16 point- 220V AC: Input/Output, 8 point- 24V DC: Input/Output/Combination, Sink/Source, Protected, Electronically Fused, Diagnostic, 8, 16, and 32 point- 48V DC: Sink Input/Source Output, 16 point- Relay: Sink/Source, 8 point Isolated inputs and outputs can be used in applications such as motor control centers where individual control transformers are used. Protected outputs (P) have electronic protection which acts to shut the output down in reaction to a short circuit, overload, or overtemperature condition.Recovery from shutdown is automatic upon removal of the output fault. No fault status is provided to the processor. Electronic Fused (EP) module acts to open the output when a fault occurs.
