M1.Phototube Coupling is used between main circuit input/output terminal and positive and negative control terminal, dielectric is pressure-resistant to be more than 2000 Vac.
2nd, in module A to and B changed between and set hardware-software to interlock in control terminal, effectively prevent forward-reverse switch
Simultaneously turn on.
3rd, module has power-on protective circuit, no surge impact, strong antijamming capability, reliability height.Controllable silicon is made pottery using DCB
Porcelain substrate, current specification 15A-90A.
4th, emitting led pipe shows motor direction of rotation, is halted state when two paths of LED does not all work（It is not drawn into figure）.
5th, it is 12-24Vdc to input control voltage, and common anode or common cathode can any wiring.When control line common anode connects, A-,
B-end low level is effective, when A-, B-end simultaneously be low level when module close automatically.When common cathode connects, the high electricity in A+, B+ end
Flat effective, when A+, B+ end are simultaneously high level, module is closed automatically（Do not drawn in the circuit diagram）, other control voltages can also determine
System.
