4. Functionality
The PIO-32/32L(PC) functions as a digital interface between a PC and external control equipment. Each input channel detects DC voltage levels (12–24 VDC) and transmits the corresponding logic state to the PC. The opto-coupler isolation ensures that electrical noise or surges from external devices do not affect the PC’s internal circuits.
The output section uses open-collector transistors to drive external loads such as relays, LEDs, or solenoids. Each output can sink up to 150 mA at 35 VDC. The positive common configuration allows the use of a shared positive supply line for all channels.
Typical Applications:
