Interface configuration:
Safety interface: Three-channel PROFIsafe, supporting SIL 3 certification, fault response time < 1ms.
Human-machine interface: Equipped with a 5.7-inch touch screen with a resolution of 640×480, it supports multi-language and gesture operation, facilitating human-machine interaction.
Communication interface: Equipped with 2× Gigabit Ethernet, supporting protocols such as Modbus TCP, OPC UA, DNP3, etc. There are also 1× RS-485 and 1×CANopen interfaces, which can facilitate data communication and system integration with other devices.

Protection performance: The EMC protection conducted emission meets CISPR 11 Class A, the radiated emission meets EN 55032 Class A, and has passed the IEC 61000-4-4 4kV electrical fast transient burst immunity test. It can work stably in a complex electromagnetic environment.

Application field:
Power industry: It can be used in power plants to ensure the stability of generator frequency. By precisely controlling the rotational speed of the turbine, the generator can stably output electrical energy to meet the power supply requirements of the power grid. It is applied in large thermal power plants, hydropower stations and gas-fired power plants.

In the oil and gas industry: During the extraction, transportation and processing of oil and gas, there are many rotating devices that require precise speed regulation, such as compressors and pumps. The 9907-164 can provide reliable speed control for these devices, ensuring the stable operation of the production process and improving energy utilization efficiency.
Manufacturing industry: It is applicable to various manufacturing equipment that requires stable speed control, especially in production processes driven by steam turbines. By operating the single extraction and/or intake of the turbine, the steam turbine can be controlled, thereby providing stable power for related production equipment.

In the aviation field: It can be used for the speed control of aero engines to ensure that the engines maintain a stable speed under various flight conditions, thereby guaranteeing the flight safety and performance of the aircraft.
Mining: In mines with the risk of gas (methane) and pulverized coal dust explosions, it can be used for equipment such as hoists, belt conveyors, scraper conveyors, coal feeders, fans, local fans, water pumps and oil pumps, providing reliable speed control for these devices to ensure the safety and stability of mine production.
