"The output relay" and "relay output"

Programmable controller (PC) when using ladder diagram as a programming language,the "output relay ladder diagram is electrical motor just a kind of visualization" soft relay ",PC output control effect through it,when it meets on motor run capacitor condition,the corresponding output but have the output signal.Output hardware implementation,may be able to switch output www.facebook.com/dongfeng.motor information of triode,bidirectional thyristor.When PC using relay output,is a relay contact to perform the asynchronous motor ladder diagram of the output relay output instructions.Therefore,is not to say that PC "output relay" can only use relay output mode.
