XC-3212 is a 12 channel 16 bit programmable pulse counter board. It is designed for industrial process control, and its main function department is as follows
It is composed of 4 pieces of 82C54. With 12 independent counters, the input signal passes through the high-speed photoelectric isolation device, Schmidt
After the circuit shaping is sent to the 82C54 counter, the CPU can get the pulse of the current pulse signal through the equivalent 82C54 operation
Number of strokes. Xc-3212 board conforms to the PC104 bus specification and can be used in all kinds of PC104 bus control computers.
