ACL-6128
Isolated 2-channel Analog Output Card


Description

The ACL-6128 is an analog output card for the IBM PC and compatibles. It contains two identical D/A converters that can be updated simultaneously. In addition to 12-bit resolution and 16 KHz throughput on each DAC, both voltage and current outputs are supported. It is an ideal analog output device for cost effective solutions in industrial applications.

The ACL-6128 is designed to meet high voltage isolation on each analog output channel. Opto-isolators give 500VDC isolation to protect both your PC and peripherals from damage due to high input voltages. In addition, a module DC-to-DC converter powers all analog circuitry, providing isolation from noise on the computer bus.

The ACL-6128 register structure and jumper settings are fully compatible with ACL-728/PCL-728.
