內容介紹：

    The PCL-728 provides two double-buffered 12-bit digital-to-analog outputs. Optical isolators give 500 volts of isolation （channel-to-channel and input-to-output） to protect the card and your PC from dangerous voltage on the output lines. You can output in several ranges: 0 to ±5 V, 0 to +10 V, ±5 V, ±10 V, 0 to 20 mA （sink） or 4 to 20 mA （sink）. The PCL-728s register format and software driver are fully compatible with the PCL-726 6-channel D/A card. This makes it easy for you to replace the PCL-726 with the PCL-728 to gain immediate isolation protection.
