Hello...
While using GM7U 40 points Transistor output, i have reversed the polarity on the output which caused a smoke and a smell to get out from the one of the outputs though the voltage was 24VDC only... and then all of the outputs were not functioning..

Any suggestions or explanations for a possile solution to the mentioned noticing that i can still install programs on it and the leds of the outputs still lights.. but the output is not activitated....

Thanks
