Product Summary
The 1794-OE4XT delivers four precise analog outputs in a compact Flex I/O package. It operates under extended temperatures and supports voltage outputs from -10 to 10V. Current loops range from 0 to 20 mA. This module requires a 24V DC external supply with a wide input range. It handles resistive loads from 15 to 750 ohms. Ideal for harsh industrial environments.
Procurement Insights for the 1794-OE4XT
Procurement managers need a module that withstands extreme conditions. The 1794-OE4XT operates reliably from -25°C to 70°C ambient. Its extended temperature rating reduces failure risk in unheated control cabinets.

The module uses single‑ended, non‑isolated outputs. This design simplifies wiring and reduces cost. Each channel delivers a nominal output voltage span of ‑10 to 10V. For current control, the range is 0 to 20 mA.
Compatibility is straightforward. The 1794‑OE4XT works with any Flex I/O bus interface. You need an external 24V DC power supply. The input range spans 19.2V to 31.2V DC, ensuring tolerance to line fluctuations.
Application engineers value the high channel density. Four outputs fit inside a single module slot. This saves panel space and reduces overall system cost. The extended temperature capability ensures stable performance in steel mills or outdoor platforms.
Technical Evaluation of the 1794-OE4XT
From an engineering standpoint, the 1794‑OE4XT provides accurate analog signals. Its voltage output resolution supports fine control loops. The current output drives actuators or I/P transducers directly.
The module supports resistive loads from 15 to 750 ohms at 24V DC. This load range covers most field devices. Signal integrity remains high due to the single‑ended design. No galvanic isolation is present, so plan wiring carefully.
Response time is typical for Flex I/O modules. The module updates outputs every 1 ms. This speed satisfies most process and discrete applications. For high‑speed servo control, consider a dedicated analog output card.
The extended temperature rating does not compromise accuracy. The module maintains 0.1% voltage accuracy across the full temperature range. Drift is minimal. This reliability reduces recalibration frequency.
Installation is simple. Mount the module on a 1794‑TB series terminal base. Wire outputs to pins 1‑4. Use shielded cable for long runs. Always connect the power supply to the correct terminals.
