FLEX I/O System
System Overview: Connects to a wide range of networks and features a modular design for high flexibility and low cost for distributed applications. Up to eight I/O modules can be connected to a single adapter, supporting a wide range of I/O point combinations.Designed for extreme environments, the FLEX I/O XT is coated for protection, meets many standards, and is resistant to a wide range of reactive substances.

Module Options
Digital I/O modules: Covering a wide range of electrical ranges such as 120V AC, 220V AC, 24V DC, etc., available in different densities from 8 to 32 points. Features isolation, protection, diagnostics, optional input filtering time, and LED status indication for each channel.
Analogue, thermocouple and RTD modules: channels can be individually configured, support online configuration, selectable input filters, etc., capable of controlling the operation of output devices under abnormal conditions, different modules have different accuracy and resolution.
Counter modules: Selected according to the type of application and field equipment, such as 1794 – IJ2XT for proportional control, 1794 – VHS for packaging, material handling, etc.
System mounting and accessories: Panel or DIN rail mounting, with grounding, using DIN rails made of zinc-plated yellow chrome steel. A wide range of accessories are available, such as extension cables, mounting kits, DIN rail latches, etc., and comprehensive documentation is also available.

FLEX Ex I/O System
System overview: Intrinsically safe for use in hazardous areas, eliminating the need for explosion-proof enclosures and additional intrinsically safe isolation components. Based on a physical architecture, categorised by hazardous area designation, connectable to a wide range of networks, modules can be plugged and unplugged electrically and have a wide range of protection features.

Module Options
Digital I/O modules: Fault detection, indication and reporting, selectable input filter time, LED status indication for each channel.
Analogue module: channel configurable, with on-board calibration, online configuration, etc., can detect over-range and under-range, and can control the operation of output devices under abnormal conditions.
Counter I/O Module: Suitable for applications such as tacho control, reports frequency, acceleration and direction, and receives and returns binary data.

System Installation and Power Supply Selection: Requires selection of the appropriate adapter and distribution method, with a variety of adapters available. Power supplies are available in N-type (vandal-proof) and E-type (fire-proof) housings, complying with North American and European standards, respectively, and offering different input voltages. The number of power supplies and their distribution need to be determined according to system planning. Documentation is available to support this.
