Detailed description of the invention
For utility model content of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and it is as follows to coordinate accompanying drawing to describe in detail.
As shown in Figure 1: have and stop latching the safe light curtain controller with hand-reset function, the described safe light curtain controller stopping latch and hand-reset function that has includes signal isolating coupler 1, signal processor 2 and relay signal output module 3；
The digital signal that described signal isolating coupler 1 transmits for safe light curtain is isolated；
Described signal processor 2 processes for the signal of signal isolating coupler transmission；
Signal is exported by controlling relay by described relay signal output module 3 for the signal of signal processor processes.
Described have the resistance R3 stopping latching the safe light curtain controller with hand-reset function 1 foot connecting photoelectrical coupler U1, outfan 3 foot of photoelectrical coupler U1 connects a foot of main control chip IC2, the outfan 4 foot ground connection of photoelectrical coupler U1, main control chip IC2 passes through electric capacity C1, electric capacity C2 is connected to signal processing and drives audion Q1, signal processing drives audion Q2, signal processing drives audion Q1 input by diode D1 ground connection, signal processing drives audion Q2 input by diode D2 ground connection, signal processing drives audion Q1, signal processing drives the outfan of audion Q2 to be all connected to the input of high frequency transformer T1, high frequency transformer T1 outfan passes through rectifier bridge ZL1, two rectifier bridges of rectifier bridge ZL2, high-frequency alternating current is rectified into unidirectional current, rectifier bridge ZL1, rectifier bridge ZL2 controls relay J 1 and 2 two relay coil energisings of relay J respectively, carry out the break-make road to external circuit to control and signal output, high frequency transformer T1 is powered by a contact of relay J 3, the coil of relay T3 is energized by a contact of a manual reset button and relay T3, to realize stopping latching and hand-reset function.
