PCI quadrature encoder board with four input channels, an interrupt controller, and one 24-bit counter. Provides inputs and decoding for up to four incremental quadrature encoders. Channels 1 through 4 available in a DB37 connector.

The PCI-QUAD04 quadrature encoder board provides input channels compatible with industry standard encoders and an interrupt controller for powerful interrupt management options. Features include integrated digital filtering, programmable indexing and multiple-counter modes.

Features:

4 input channels
The inputs are configurable for differential mode or referenced to ground
An interrupt controller offers powerful handling capabilities
All 4 receivers can tolerate long lines in noisy environments
Uses built-in digital filter and 8-bit counter prescaler
Programmable functionality
Each 24 bit counter can count in binary or BCD

Hace el trabajo bien

Buen producto y fácil de controlar. Pero necesita un método de instalar el controlador más fácil para incorporarlo en protectores OEM. La línea de salida de 12 V sería grandiosa para controlar encoders.
