Product Short Description
- Technical Specifications
- Electrical Output Parameters
It is equipped with 32 output points that are connected in pairs. The nominal input voltage is ±24V, and the operational voltage range expands to ±30V, with a maximum switching voltage of ±33V peak. Each channel has a nominal current of 0.5A and a maximum over – current capacity of 0.7A. The maximum switching power for resistive loads is 15W, and the maximum off – state leakage current is less than 100μA. When the current is 0.5A, the voltage drop at the baseplate is less than 0.25V.
- Protection and Isolation Parameters
The baseplate is equipped with a 0.75A fast – acting fuse for each output channel to achieve over – current protection for each channel. The isolation voltage between functional earth and protective earth is at least 500VDC, and the isolation voltage between functional earth and functional (logic) earth reaches a minimum of 800VDC. This strong isolation performance can effectively prevent electrical interference between different circuits.
- Physical and Environmental Parameters
It adopts mechanical keying design. This design can prevent incorrect installation of the module in the configured baseplate. The module can work normally in an environment with a temperature range of -40°C to 70°C, and it can tolerate a non – condensing humidity environment ranging from 5% to 95%. With an IP65 – rated enclosure, it can resist dust and water intrusion.

Description
- Functional Features
- Stable Solid – State Relay Performance
The module adopts solid – state relay technology instead of traditional mechanical relays. It avoids problems such as mechanical wear and contact jitter that are common in mechanical relays. It ensures stable switching of output signals even during long – term continuous operation. This feature makes it more suitable for non – critical application scenarios that require frequent switching operations and long – term reliable operation.
- Comprehensive Channel Diagnostic Capabilities
It is equipped with continuous diagnostic functions for each output channel. It can automatically detect faults occurring in each channel during operation and trigger fault indicators to send out alarm signals once a fault is found. In addition, it supports I/O loop – back testing, which can promptly discover and report problems such as abnormal signal transmission and channel failures, facilitating maintenance personnel to quickly locate and solve faults.
- Fault Tolerance and Hot – Spare Support
It has single fault tolerance. It can still operate normally when a single fault occurs, and can even maintain operation when multiple faults occur. It also supports hot – spare configuration. When a module breaks down, the hot – spare module can take over its work immediately. This realizes online replacement of faulty modules without shutting down the entire system, ensuring the continuous operation of the industrial control system.
- Convenient Installation and Maintenance
The mechanical keying structure simplifies the installation process and avoids system malfunctions caused by wrong installation. The modular design allows maintenance personnel to quickly disassemble and replace the module. Meanwhile, the independent fuses for each channel make it convenient to check and replace faulty fuses separately without affecting the operation of other channels, greatly improving maintenance efficiency.

- Application Scenarios
- Oil and Gas Industry
It is integrated into the auxiliary control systems of oil drilling platforms and natural gas transmission stations. It is mainly used to drive annunciator panels and auxiliary switching devices. It sends out timely alarm signals when parameters such as pipeline pressure and gas concentration are abnormal. It also controls the switching of some non – critical auxiliary equipment. It assists the main safety system to ensure the safety of oil and gas production, storage and transportation processes.
- Chemical Industry
In chemical production plants, it is applied in the control systems of non – critical process sections such as material batching and waste gas preliminary treatment. It controls the switching of on – site indicator lights and small – power auxiliary pumps through solid – state relay output. It cooperates with the main safety instrumented system to realize real – time feedback of equipment operation status. It avoids production interruptions caused by minor faults in auxiliary equipment and maintains the stability of the entire chemical production line.
- Power and Nuclear Power Industry
In thermal power plants, gas power plants and nuclear power plants, it is used in the auxiliary control systems of power generation equipment such as boilers and turbines. It is responsible for the signal switching of non – critical components such as equipment status display panels and auxiliary cooling system switches. When minor abnormalities occur in auxiliary equipment, it can send alarm signals in time. It ensures that operators can handle the problems promptly without affecting the operation of the core power generation system, thus ensuring the stable supply of electric energy.
- Metallurgical and Pharmaceutical Industries
In metallurgical plants, it is used in the auxiliary control of smelting auxiliary equipment to control the switching of temperature indicator lights and feeding auxiliary mechanisms. In pharmaceutical factories, it is integrated into the control systems of non – core production links such as drug packaging and material transportation. It drives the switching of relevant auxiliary equipment through reliable solid – state relay output. It ensures the orderly progress of these auxiliary processes and indirectly guarantees the efficiency and safety of the core production processes.
