Brand: Dual

Dual 1237 A is a computer expansion card that provides two additional 12-bit ISA-compatible programmable timer/counters (PTCs) with attendant hardware interrupts, status flags, and input/output registers. These PTCs are ideal for synchronous and real-time control applications that require precise delays, periodic interrupts, frequency measurement, and pulse width modulation. Each PTC has its own frequency input terminals, prescaler divider, capture input, output compare, and software latch control. The Dual 1237 A is typically installed in a full-height, 32-bit ISA or PCI expansion slot on an IBM-compatible computer running MS-DOS, Microsoft Windows, or some variations of OS/2.
