SET-1320 32Ch Isolated Output Card

The SET-1320 device is an isolated digital output interface for NI-SLSC. This card provides 32 optically isolated open-collector outputs that can switch up to 100 mA at 60 V DC. SET-1320 combines high-density IO with high isolation voltages and a wide output voltage range. It allows to break ground loops and protect susceptible test equipment from DUTs. It also enables to interface standard logic-level test equipment with almost any system voltage. The SET-1320 can be driven through the RTI or through the SLSC chassis via software. RTI inputs are compatible with LVTTL and TTL logic levels.

The SET-1320 has 32 optically isolated open-collector outputs. Current can flow from CH+ to CH when the output is on. The outputs are reverse polarity protected to -60 V DC. The outputs are controlled from a logic-level digital output source, like NI R-Series FPGA or NI C-Series digital output modules, through the RTI.
