Features:
- Eight resistance inputs: RTD temperature and direct resistance measurement
- Multiple lead topologies: documented two-, three-, and four-wire connections
- Open-wire visibility: channel diagnostics for broken sensor circuits
1794-IR8 converts resistance-based sensors, not thermocouple junction voltage, inside a FLEX I/O station.
Its measurement quality is governed by the selected curve and the way lead resistance is handled.
The channel record should identify sensor standard, wiring topology, terminal base, scaling, and traceable test results.
Apter Power can coordinate official-document review, quotation, and sourcing support for 1794-IR8.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Two-wire: apply the official jumper and lead arrangement for the channel.
- Three-wire: land the compensation pair exactly as shown in the module diagram.
- Four-wire: preserve separate source and sense conductors to the approved terminals.
- Sensor curve: choose the exact RTD standard or resistance range.
- Controller format: interpret the documented implied decimal and engineering units.
- Traceable check: compare several resistance points across the operating span.
- Routing: separate sensor cables from switching power and high-noise conductors.
- Shielding: terminate shields according to the official grounding instructions.
- Diagnosis: use open-wire status and resistance checks before changing filters.
- RTD temperature points: acquire supported resistance-temperature sensors.
- Direct resistance: measure documented resistance ranges without thermocouple compensation.
- Distributed monitoring: collect eight low-level channels in a FLEX I/O station.
