It can meet the needs of various complex application scenarios by virtue of its flexible expandability, high degree of integration and multiple I/O types.

Key Features

Flexible expandability:

The module features an additional slot that supports hot-swapping and allows for the insertion of various option modules (POMs), including USB, Ethernet, RJ12RS-232, 3PINRS-485 and 3PINRS-232 versions.

This design allows users to change network configurations on demand as communication needs change, thus increasing system flexibility and adaptability.

Highly integrated:

The module requires no chassis or backplane and can be expanded with up to 8 I/O modules (depending on the model used).

It is available in 27 discrete I/O expansion module versions, including 8-point, 12-point and 16-point versions, enabling the system to be expanded to a maximum of 164 discrete I/O points.

Multiple I/O module types:

I/O modules include two main types: analogue and switching.

Each I/O module can be plugged directly into a terminal board either locally on the CPU or via FBP distributed expansion sub-stations.

CPU local can be expanded up to 10 I/O modules (firmware version V1.2 or above), while distributed sub-station can be expanded up to 7 I/O modules.

The IO module has the following main functions

Input Function

The IO module can receive input signals sent by external devices and convert them into digital or analogue signals for use by the computer system or control system. These input signals can come from a variety of sensors, such as temperature sensors, pressure sensors, photosensitive sensors and so on. By receiving and parsing these input signals, the system can monitor and control the external environment in real time.

Output Functions

The IO module is capable of converting the output signals generated by a computer system or control system into the form required by an external device. These output signals are typically used to control actuators such as motors, valves, lights, etc. By sending appropriate output signals to external devices, the system enables control and operation of the external environment.

Data Acquisition and Processing

The IO module is capable of acquiring data from external devices and transferring it to a computer system or control system for further processing. This enables the system to acquire environmental data, status information and user inputs in real time and make appropriate decisions or perform specific tasks based on these data.

Communication Interfaces

IO modules are usually equipped with different types of communication interfaces, such as serial interfaces (RS232, RS485), Ethernet interfaces, CAN bus interfaces, and so on. These interfaces enable IO modules to exchange data and communicate efficiently with computer systems or other external devices.
