SA40 Series

The SA40 controller adopts a modular structure design and has the characteristics of rich functions, high integration, excellent performance, high reliability, good scalability, and ease of use. It can provide personalized solutions for different industrial fields and can be widely used in Tunnels, transportation, water treatment, chemical industry, energy, heating, electric power, building materials, pharmaceuticals, metallurgy and other industries.

In addition to the requirements of traditional PLCs, the SA series PLC also focuses on interconnection. For industrial sites, it can be used for remote rack expansion and third-party communication through various industrial field buses such as EtherCAT, Profinet, Modbus TCP, ModbusRTU.CANopen, etc. Device interconnection is aimed at industrial configuration, and it can interact with various industrial configuration software through standard communication protocols such as OPCUA Server, Modbus TCP, Modbus RTUMQTT, and user-defined network protocols.


1. Rich bus support, supporting industrial communication protocols such as EtherCAT, MODBUS-TCP, CANopen, RS485;

2. Comes with local IO, supports 16 channels of input and 16 channels of sink output;

3. Rich expansion, supporting multiple types of IO modules;

4. Powerful performance, can connect 32 axes;



Rail installation

① Pull down all the buckles on the back of all modules in the module group (as shown in Figure 1). It should be pulled until it clicks.
