Features:
- Four differential inputs: provides analog acquisition for compact SLC applications
- Mixed signal choice: each channel can use the documented voltage or current range
- 16-bit conversion: supports scaled process measurements with a defined 60 ms response
1746-NI4 allows a small SLC system to combine voltage and current inputs without dedicating one module to each signal type.
Its value depends on channel-by-channel mode and scaling records that follow the physical loop.
Differential wiring improves measurement control but does not remove grounding, shielding, or common-mode design requirements.
Apter Power can review 1746-NI4 channel modes, terminal block, official records, condition, and exact sourcing requirements.

- Per-channel choice: document voltage or current mode for every loop
- Source compatibility: match the transmitter output and test equipment to the selected range
- Scaling pair: retain raw and engineering-unit endpoints with the channel record
- Differential pair: keep each signal and return together through the cable route
- Shield termination: follow the approved single-point grounding practice
- Potential review: prevent loop references from exceeding the documented input boundary
- Known source: inject low, midpoint, and high values for each selected range
- Response check: allow for the documented conversion and step behavior
- Program proof: compare raw counts, scaling, alarms, and displayed engineering units
- Process transmitters: acquire supported current-loop measurements
- Voltage sensors: read differential signals within the selected ±10 V range
- Mixed analog panel: combine current and voltage channels in one compact SLC slot
