(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。

(1) Relay output: the advantage is that there can be different AC and DC loads between different common points, and the voltage can also be different, and the load current can reach 2A points; However, the relay output mode is not suitable for the load of high frequency action, which is determined by the life of the relay

(2) thyristor output: with load capacity of 0.2A/ point, only with AC load, can adapt to high-frequency action, response time is 1ms (3) transistor output: The advantage is that it is suitable for high-frequency action, the response time is short, generally about 0.2ms, but it can only take DC5-30V load, the output load current is 0.5A/ point, but every 4 points shall not be greater than 0.8A.

When your system output frequency is less than 6 times per minute, should relay output, because of its simple circuit design, anti-interference and load capacity is strong when the frequency is less than 10 times /min, both relay output mode can be used, and PLC output can be used to drive Darlington transistor (5-10A), and then drive the load.
