The nominal voltage is 120VDC, and the applicable voltage range spans from 90VDC to 150VDC. The typical voltage drop of the module is less than 1.5V. Each of its 16 commoned output points supports a maximum current of 0.8A, and can withstand a 4A surge current lasting for 10ms. The maximum load leakage current is 2mA at 60Hz. Each output point is equipped with a separate 1.0A fast-acting fuse to protect the circuit from overload damage, and the point isolation capacity reaches 1500VDC/2500VDC.
The module weighs 3.65kg, featuring a compact structure that is suitable for installation in space-constrained control cabinets. It operates stably within a temperature range of -20°C to +70°C. Its robust industrial-grade material structure enables it to resist the harsh conditions of industrial sites, ensuring long-term reliable operation without being easily affected by mechanical vibration or environmental corrosion.
It adopts triple modular redundancy technology and quadruplicated voting circuitry. Three independent channels simultaneously process the same output signal, and the voting circuit screens out the most accurate signal for output. This structure enables the module to automatically achieve failover when a single-point failure occurs, and still maintain normal operation even if individual channels break down, thus maximizing the safety and availability of the entire control system.
It is equipped with a voltage loopback circuit that can verify the operation of each output switch and detect hidden faults timely. It is also configured with multi-group diagnostic indicators, including indicators for the on-off state of each output point, and module status indicators showing pass, fault, and active conditions. In addition, there are load and fuse alarm indicators for each output point that can immediately send out alarm signals when abnormalities such as load failure or fuse burnout occur, facilitating rapid troubleshooting.
The module supports hot-swap functionality. Maintenance personnel can replace the faulty module without shutting down the entire industrial control system, which significantly reduces system downtime and improves operational continuity. The mechanical keying design prevents wrong installation during module assembly, avoiding system malfunctions caused by misinstallation and ensuring the correctness of the system structure.
It supports multiple industrial communication protocols, which allows seamless data interaction with various programmable logic controllers and upper computer systems. It can be quickly integrated into existing Triconex safety control ecosystems without the need for large-scale modification of the original system infrastructure. The matching external termination panel simplifies field wiring operations and enhances the convenience of on-site installation and later maintenance.
It is widely used in oil drilling platforms, natural gas transmission stations and refineries. It outputs control signals to executive components such as emergency shutdown valves and pipeline isolation valves. When dangerous situations like oil and gas leakage or pipeline overpressure happen, it can promptly send reliable signals to trigger emergency shutdown procedures, preventing the spread of hazards and minimizing property losses and safety risks.
In chemical production plants, it is applied to the control systems of reaction kettles, storage tanks and material conveying pipelines. It controls the on-off operation of dosing pumps, discharge valves and other equipment. It ensures that each step of the chemical production process strictly follows preset procedures. When abnormal parameters occur in the production process, it can quickly adjust the output signal to stop relevant operations, avoiding explosions or toxic gas leakage caused by process disorders.
It is integrated into the safety control systems of thermal power and nuclear power plants, mainly used to control protective components such as turbine emergency trip devices and boiler safety valves. It monitors the operating state of key power generation equipment in real time. When equipment faults such as generator overheating or boiler pressure anomalies occur, it can immediately send control signals to cut off dangerous operations, ensuring the stable operation of the power generation system and protecting the safety of the power grid.
In steel and non-ferrous metal smelting workshops, it is used in the control systems of smelting furnaces, continuous casting machines and other core equipment. It outputs signals to control the switches of feeding mechanisms, cooling water valves and exhaust devices. It ensures the stability of smelting temperature and process flow. It prevents production accidents such as furnace explosion due to equipment failure, and guarantees the continuity and quality of metallurgical production.
