32-Channel, 60 V Optical Isolator—The SET-1320 is an isolated digital output interface for NI-SLSC. It provides 32 optically isolated, open-collector outputs that can switch up to 100 mA at 60 V and features galvanic channel-to-channel and rack isolation and high sensitivity of current digital input. The SET-1320 combines high-density I/O with high isolation voltages and wide output voltage range with outputs that are reverse polarity protected up to -60 V. It breaks ground loops and protects susceptible test equipment from DUTs, enabling DUT characterization for parametric testing. You can control this device from a logic-level digital output source, such as a C Series Digital Module or PXI Digital I/O Module.
