SMX-3002DS high-density multiplexer module consists of eight individual (1 x 8) 2-wire multiplexers. In contrast to the SMX-3002 the SMX-3002DS has internal residual voltage discharge relays that can be enabled to momentarily short out the measurement path when changing from one input channel to the next. This dissipates any voltage held by the wiring and instrument input capacitance. These relays protect sensitive devices, such as CMOS circuits, from residual voltages caused by previous high-voltage measurements. This feature can also be disabled in low-voltage applications where maximum throughput speed is important. The SMX-3002DS can be controlled programmatically using IviSwtch-compliant calls. Both path level programming and individual relay control are available.
