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 inputs and 16 TTL digital outputs. The features of the ACL-6126 are:
1. 6 Independent 12-Bit D/A Converters
Each output channel is jumper selectable for the following output ranges:
Unipolar: 0~5V, 0~10V
Bipolar: ±5V, ±10V
Current Loop: 4-20mA (sink)
2. Digital I/O
There are 32 TTL compatible digital I/O (16 inputs and 16 outputs) via two 20-pin
connectors. The digital I/O can be used to control multiplexers, read external status, etc.
3. Interrupt Control
With the interrupt control circuitry, one external interrupt trigger pin on the digital
I/O connector can cause an interrupt request. IRQ3 to IRQ15 is jumper selectable.
4. State-of-the-Art Design
The compact sized PCB design makes the ACL-6126 suitable for embedded or
space critical applications. Also, the surface mount technology of this card improves its
quality and reliability.
