product overview
The FlexE series expansion I/O is an extension of the integrated RTU product of Sichuan Ankang Technology Co., Ltd., which enhances the expansion function of the integrated RTU. The FlexE series expansion I/O products can be used independently as remote I/O, or as expansion modules for Super32 series RTUs combined with integrated RTUs. This series of I/O products has standard communication interfaces, which can be easily integrated with standard products from other companies.

The FlexE series expansion I/O products from Ankang Technology, with their excellent performance and high flexibility, not only enrich the application scope and fields of integrated RTUs, but also enable all automation integrated RTUs to be expanded at low cost, greatly reducing the cost of system expansion. Wireless communication technology is also a major feature of this series of products. The FlexE series expansion I/O can be connected to the automation system through advanced wireless communication network technology, eliminating construction costs caused by wiring.

The FlexE products of Ankang Technology are divided into the FlexE 31X, FlexE 51X, and FlexE 53X series. The FlexE 31X is a remote I/O module that can be extended through RS485 and CAN, while the FlexE 51X is a remote I/O module that can be extended through Zigbee. The FlexE 53X can serve as the CPU for the FlexE series remote I/O modules.

Product Features
The product is installed on-site in the industrial field. Users can use the FlexE series I/O to build systems in a more convenient way. Connect instruments, drivers, valves, switches, etc. locally and communicate remotely with the upper computer.
Industrial grade design, easy to install and connect. Users can install modules on DIN rails without the need for temperature control devices such as heating belts or fans inside the cabinet.
Real time monitoring of remote data to reduce project costs. Adopting the RS485 serial bus standard, it has the ability to suppress common mode interference. It is very convenient for multi-point interconnection and can save a lot of signal lines. By adopting wireless networking, the system structure is more flexible, and wireless communication can even replace wired communication signal lines.
Standard signal extraction, standard communication protocol facilitates system access and expansion. The FlexE series I/O adopts the most common signal input and output types, and some models integrate input and output into one, which can connect the vast majority of field instruments. By using the standard Modbus protocol, it can be connected to common configuration software, touch screens, and industrial computers.

application area
The FlexE series extended I/O is designed for highly reliable industrial applications in harsh environments, and can be applied to various fields including oil and gas field production, oil and gas storage and transportation, coalbed methane, shale gas, municipal gas, heating networks, water affairs, environmental protection, etc.

CAN bus extension

In the data measurement and control stations of oil and gas production well sites, pipeline networks, and other industries, the FlexE 31X series I/O modules are used as extensions of RTUs and other controllers to supplement the insufficient number of I/O points. Up to four I/O modules can be expanded through the CAN bus. Industrial grade design, no need for fans or heating equipment inside the chassis, can be directly installed for outdoor use.

RS485 bus connection

The FlexE 31X series I/O modules can be applied to industries such as agriculture and water conservancy. We use RTU controllers or industrial servers as the main control unit, adopt RS485 serial bus, with a maximum laying distance of 1200 meters, and each 485 interface can connect up to 31 I/O modules, which can effectively reduce inconvenience such as multiple cables and large construction volume.

The FlexE 31X can also be connected to SCADA system as a remote terminal through RS485 interface or with DTU, data transmission radio, etc., and directly exchange data with HMI.
