The Smart E Tech SET-1320 Optical Isolator (Part Number: 785671-01) is a robust 32-channel device designed for seamless integration with National Instruments SLSC systems. Capable of handling up to 60 Volts, this optical isolator features open-collector outputs that can switch currents of up to 100 mA while providing high isolation voltage and rack protection. It prevents ground loops effectively, ensuring test equipment remains protected from devices under test (DUTs). The SET-1320 is compatible with TTL and LVTTL logic levels, allowing for easy control from various logic-level digital output sources, such as PXI Digital I/O Modules or C Series Digital Modules. Incorporating reverse polarity protection, it safeguards against damage from voltages as low as -60 VDC. The device allows current flow from the positive channel (CH+) to the negative channel (CH-) when in the ON state, while the reverse polarity protection inhibits current from flowing in the opposite direction. Across its non-adjacent pins, the SET-1320 supports up to 120 VDC of isolation, providing up to 60 VDC isolation between adjacent channels and from the chassis ground. With dimensions of 5.68 x 1.2 x 11.88 inches, the SET-1320 is an essential component for testing and measurement applications, particularly in DUT characterization and parametric testing.
