GE SR469-P5-HI-A20-E CPU模块 DCS备件
GE 电机保护装置SR469-P5-HI-A20-E CPU模块 DCS备件 方式选择 (1)继电器输出:优点是不同公共点之间可带不同的交直流负载,且电压也可不同,带负载电输出回路设计注意事项: 3.1、输流可达2A 点;但继电器输出方式不适用于高频动作的负载,这是由继电器的寿命决定的 (2)晶闸管输出:带负载能力为0.2A/ 点,只能带交流负载,可适应高频动作,响应时间为 1ms (3)晶体管输出:优点是适应于高频动作,响应时间短,一般为0.2ms左右,但它只能带DC5-30V的负载,输出负载电流为0.5A/点,但每4点不得大于0.8A。当你的系统输出频率为每分钟 6 次以下时,应继电器输出,因其电路设计简单,抗干扰和带负载能力强 当频率为 10 次/min 以下时,既可采用继电器输出方式,也可采用PLC输出驱动达林顿三极管(5-10A),再驱动负载。

Points for attention in output circuit design: 3.1. Selection of output mode (1) Relay output: The advantage is that different AC and DC loads can be brought between different public points, and the voltage can be different, and the loaded current can reach 2A points; However, the relay output mode is not suitable for the load with high frequency action, which is determined by the service life of the relay. (2) Thyristor output: the load capacity is 0.8A/ point, only AC load can be brought, and the response time is 1ms. (3) Transistor output: the advantage is that it is suitable for high frequency action, and the response time is short, generally about 0.2ms, but it can only carry the load of DC5-30V, and the output load current is 0.5A/. When the output frequency of your system is less than 6 times per minute, it should be output by relay. Because of its simple circuit design, strong anti-interference and load-carrying ability, when the frequency is less than 10 times /min, you can use relay output mode or PLC output to drive Darlington transistor (5-10A) and then drive the load.
