Key Technical Specifications

Product Introduction

This NI SCXI-1104C is a legacy SCXI signal conditioning module built for low-frequency voltage measurement. It multiplexes 32 differential input channels and applies fixed 2 Hz filtering to suppress line noise before sending signals to a DAQ device.

It works well for steady-state sensor readings where high-frequency content is not needed. Many test stations retain this hardware because rewriting LabVIEW code and reworking wiring for newer platforms adds extended downtime.

Application Scenarios & Field Experience

This conditioning module is a common spare on older fixed test benches. A failed module breaks all 32 sensor channels, and operators cannot split the measurement load across remaining hardware.

1. Automotive component testing: Long-duration thermal soak and voltage monitoring racks
2. Energy monitoring: Slow sampling of DC bus and battery bank voltage points
3. Aerospace validation: Static structural test strain and voltage monitoring
4. Industrial machinery: Slow-response temperature and pressure sensor logging

I supported a structural test bench outage where this SCXI-1104C stopped multiplexing channels. The test software returned stale readings, and the ongoing load test could not continue safely. We swapped the spare module, verified chassis addressing, and restored all 32 channels in 27 minutes. The test team avoided aborting a multi-hour load cycle.

Standard Operating Procedure (SOP) for Quality Control

1. Visual & Origin Inspection: Check OEM labeling, edge connector pins, terminal header condition, and anti-counterfeit validation; reject units with cracked PCB traces or unapproved component rework.
2. Live Rig Testing: Install into a compatible SCXI chassis, run channel scan sequence, verify filter response and stable channel routing to a DAQ controller.
3. Firmware Verification: Read and log module configuration ID; confirm compatibility notes for legacy DAQ driver versions before shipment.
4. ESD-Safe Packaging: Seal the module inside static shielding bag, add rigid foam around the edge connector, mark cartons for ESD handling.

Frequently Asked Questions (FAQ)

Q1: Can I drop this SCXI-1104C into any SCXI chassis without pre-checks?A: Confirm your chassis model and DAQ driver version first. Newer NI-DAQmx releases have limited support for this legacy module, and incorrect chassis addressing creates channel cross-talk.

Q2: What warranty coverage comes with this part?A: We provide a 12-month warranty starting from delivery date. Warranty covers factory defects; overvoltage input damage, miswiring, or incompatible driver configuration are excluded.

Q3: How quickly can this unit ship once I place an order?A: If marked in stock, we pack and ship within 1 business day. We confirm stock before payment, as SCXI hardware is end-of-life and available inventory is limited.

Q4: What risk occurs if the module configuration ID does not match the existing test setup?A: Mismatched settings can cause channel misrouting, incorrect scan order, or the DAQ software failing to recognize the module. Share your existing hardware profile before ordering.

Q5: Can I hot-swap this SCXI module while the chassis remains powered?A: Do not hot-swap. Power down the SCXI chassis and wait for backplane p
