The ISO-DA8 is bus-type isolated 14-bit D/A card for PC/AT compatible computers. The optical isolation of the ISO-DA8 can operate with up to 2500Vrms of common-mode voltage. The ISO-DA8 offers 8-channel, double-buffered analog output. The output range may be configured from these ranges : ±10V, ±5V, 0 ~10V, 0 ~5V voltage output or 4 to 20mA or 0 to 20mA current loop sinking.
