Introduction
The PC 62C is an enhanced IRQ Optical Isolated Input Board for the IBM PC/XT/AT, 486,
Pentuim, ISA and EISA Computers. It provides 16 / 64 Optically Isolated Inputs in either
single ended or differential mode.
16 Digital Inputs and 16 Digital Outputs (with open collector outputs) are also provided on the
PC62C.
The PC 62C fits into one of the IBM PC/AT, ISA, EISA expansion slot.
Typical applications
Industrial control
Process Control
Laboratory Automation
Energy management
Product testing
