求翻译：用于驱动电磁阀、接触器、小功率电动机、灯和电动机起动器等负载。模块将S7-300的内部电平转化为控制过程所需的外部电平，同时用隔离和功率放大的作用。是什么意思？

For driving electromagnetic valves, small power motors, lamps, and motor contactors, starters and other loads. Module S7-300 the inner level into required for the control process of external level, both isolation and power amplifying effect.

For solenoid valves, contactors, low-power electric motors, lights and electrical machinery such as starter load. Module 7 - 300 S internal power into control over the process the required external power, and at the same time using segregation and power amplifier.

Uses in actuating loads and so on solenoid valve, contact device, fractional electric motor, lamp and electric motor starter.The module transforms the S7-300 internal level exterior level which needs for the controlled process, simultaneously uses the function which the
