Product Description

The 1794‑IE4XOE2 from Allen‑Bradley is a high‑density Flex I/O combination module. It integrates four single‑ended, non‑isolated analog inputs and two single‑ended, non‑isolated analog outputs in one compact unit. Ideal for distributed I/O architectures, it handles current (0‑20 mA, 4‑20 mA) and voltage (±10V DC, 0‑10V DC) signals. The built‑in ADC uses successive approximation (SAR) with 12‑bit unipolar / 11‑bit plus sign resolution. Outputs use PWM conversion for accurate control. This module is fully compatible with 1794‑TB2, ‑TB3, ‑TB3S, ‑TB3T, ‑TB3TS terminal bases.

Diagnostics & Typical Applications

Diagnostic capabilities: Per‑channel overrange/underrange detection, open‑wire detection (4‑20 mA), module status via FlexBus. The 1794‑IE4XOE2 provides real‑time data for predictive maintenance.

Typical applications: Process control (flow, pressure, temperature), actuator control (valves, dampers), test stands, OEM machinery, and retrofits in legacy systems. Ideal for distributed I/O nodes requiring mixed analog signals.

FAQ – Quick Answers

• Q: Can I mix current and voltage on the inputs?
  A: Yes, each of the 4 inputs is independently configurable for 0‑20mA, 4‑20mA, ±10V, or 0‑10V.
• Q: Does this module provide isolation?
  A: No, all inputs and outputs are single‑ended and non‑isolated. Use external isolators if required.
• Q: What terminal base fits?
  A: 1794‑TB2, ‑TB3, ‑TB3S, ‑TB3T, ‑TB3TS. Choose based on wiring needs.
• Q: Is the module hot‑swappable?
  A: Yes, in most Flex I/O systems, but verify with your adapter.
• Q: What is the warranty?
  A: 12‑month warranty against defects from Oiltech Controls.
