Product Overview
National Instruments SCXI-1163 is a 32-channel optically isolated digital output module for the NI SCXI signal conditioning platform. Organized into 8 isolated banks of 4 channels each, it delivers 250 Vrms bank-to-bank and bank-to-earth optical isolation - protecting the host computer and DAQ system from high-voltage transients, ground loops, and electrical noise generated by industrial field equipment. Each bank accepts an external user-supplied +5V logic source. Logic-level commands from NI-DAQmx or LabVIEW drive the isolated outputs to switch external loads such as solenoids, relays, and actuators. Compatible with SCXI chassis including the SCXI-1000, SCXI-1000DC, and SCXI-1001. Manufacturer part numbers: 182247G-01, 776572-63.

- UL and CE certified; Rev 3.0
Applications
- Drop-in replacement for a failed SCXI-1163 in an existing production line test stand - slide into the chassis slot, secure thumbscrews, reconnect the terminal block, and verify in NI MAX without touching the existing software codebase
- Programmatic control of solenoids, relays, or actuators from a LabVIEW test sequence in an aerospace or industrial R&D lab, where optical isolation protects the control computer from field-side voltage transients
- Expanding digital output capacity in an automated test equipment rack by adding a chassis slot dedicated to isolated switching of 32 independent field-side lines
- Controlling external indicator lights, alarm outputs, or relay-driven loads in a multi-channel process monitoring system where ground-loop elimination is required
Frequently Asked Questions
Which SCXI chassis is this module compatible with?
The SCXI-1163 is compatible with NI SCXI chassis including the SCXI-1000, SCXI-1000DC, and SCXI-1001. It cannot operate as a standalone device and requires a chassis, a compatible NI DAQ controller, and NI-DAQ software on a host PC.
What terminal block do I need to wire field signals to this module?
Compatible terminal blocks include the SCXI-1326, SCXI-1327, and TBX-1326. The terminal block is not included with this module and must be sourced separately.
Does this module work with modern NI-DAQmx drivers and current operating systems?
The SCXI platform is classified as mature and legacy by National Instruments. Buyers running newer 64-bit operating systems or current NI-DAQmx driver versions should confirm SCXI hardware support for their specific software environment before purchase.
Does the module supply its own output power to the field side?
No. Each bank requires an external user-supplied +5V ±0.5V Vcc source. The chassis does not supply field-side logic power. Typical current draw is 60 mA per bank, maximum 80 mA per bank.
What is the difference between the SCXI-1163 and the SCXI-1163R?
The SCXI-1163 uses standard optocouplers for its isolated outputs. The SCXI-1163R uses solid-state relays instead, designed for switching higher current loads. This listing is for the standard SCXI-1163.
Thirty-two isolated channels, eight banks, one slot in the rack - and a government lab's worth of quiet hours behind it. The next chapter is yours to write.
