Description

The ACL-6126 is an analog output and digital I/O card for the IBM PC/AT and compatibles. It provides 6 channels of 12-bit analog outputs, 16 TTL compatible digital input and 16 TTL digital outputs.

Each output channel is jumper selectable for the foloowing output ranges: unipolar: 0~5 V, 0~10 V; bipolar; ±5 V, ±10 V, current loop 4-20 mA (sink)

There are 32 TTL compatible digital I/O (16 input and 16 outputs) via two 20-pin connector. The digital I/O can be used to control multiplexers, read external status, etc.

With the interrupt control circuitry, one external interrupt trigger pin on the digital I/O connector can cause an interrupt request. IRQ3 to IRQ15 can be set by jumper selection.

The compact size PCB design makes ACL-6126 suitable for embedded or space critical applications. Most of the components used on the card are place dusing surface mount technology. This greatly improves the quality and reliability of this card.
