This product is a PCI bus supported board that extends the analog signal output functions of a PC. Equipped with four channels of 16-bit analog output, the product is an individual isolation model using a D/A converter for each channel to provide isolation for the bus line with PC and between channels. The voltage/current output range (voltage : ±10V, 0 - +10V; current : 0 - 20mA) can be set by jumper for each channel. This product can generate signals that are synchronized with the internal timer or an external clock. Windows/Linux driver is supported with this product.
