Product Overview

The Allen-Bradley 1794-IE4XOE2 FLEX I/O™ Hybrid Analog Module integrates 4 isolated analog inputs and 2 analog outputs in a single IP67-rated package for distributed process control. Designed for Rockwell's FLEX platform, this epoxy-sealed unit (-40°C to +70°C) handles voltage/current signals while withstanding high-pressure washdowns, oils, and chemicals.
Dual 24-bit delta-sigma ADCs (inputs) and 16-bit DACs (outputs) achieve ±0.05% FSR accuracy, with 250V AC channel-to-channel isolation eliminating ground loops. Embedded diagnostics include open-circuit detection, NAMUR NE43 alarms, and timestamped drift alerts. Compatible with Studio 5000® for seamless configuration of thermocouple/RTD inputs (Type J/K/T/Pt100) and 4-20mA/±10V outputs.

 
Critical Technical Specifications
Core performance metrics:
  • Inputs: 4× software-configurable (TC/J/K/T/E, RTD Pt100/1000, ±50mV, ±10V, 0-20mA)
  • Outputs: 2× 0-20mA/4-20mA current or ±10V voltage
  • Resolution: 24-bit (inputs), 16-bit (outputs)
  • Accuracy: ±0.05% FSR @25°C (inputs), ±0.1% (outputs)
  • Isolation: 250V AC I/O-to-I/O, 1500V AC field-to-backplane
  • Update Rate: 8ms/channel (all points scanned ≤32ms)
  • Power: 120mA @5V logic, 240mA @24V field
  • EMC: EN 61326-1 (10V/m RF immunity), ±4kV surge (IEC 61000-4-5)
  • Certifications: SIL 2, ATEX II 3G, IECEx, DNV-GL
 
Targeted Applications
Demanding hybrid I/O scenarios:
  • Chemical Processing: Reactor temperature monitoring (TC) + reagent valve control (4-20mA)
  • Pharmaceuticals: Cleanroom pressure sensing (0-10V) + sterile air valve modulation
  • Food Processing: Fryer oil temp (RTD) + conveyor speed control (±10V) in EHEDG zones
  • Energy Generation: Turbine vibration (IEPE ±50mV) + lube oil flow control
  • Water Treatment: pH sensing + chlorine pump output with corrosion-resistant terminals
  • HVAC: Duct static pressure + VFD speed regulation

Ideal for reducing panel footprint in safety-instrumented systems (SIL 2) with analog closed-loop control.

 
Competitive Advantages
Design superiorities:
  • Space Optimization: Replaces 6 modules with 75mm DIN width (60% space saving)
  • Calibration-Free Operation: Auto-zero compensation ±5ppm/°C drift over 5 years
  • Diagnostic Depth: Detects 0.5Ω RTD wire degradation and 4.2mA output shorts
  • Safety Integration: SIL 2 certification without external barriers
  • Wiring Economy: 1794-TB3S push-lock terminals (installation in <90 seconds)
  • Mixed Signal Flexibility: Simultaneous TC/RTD/voltage/current on single module
  • Extreme Environment Operation: -40°C cold start capability (validated per EN 60068-2-1)
 
Functional Capabilities
Advanced process integration:
  • Predictive Scaling: Auto-detects sensor failures beyond 20.5mA/10.5V
  • Waveform Synthesis: Output sine/triangle waves (0.1-500Hz) for actuator testing
  • Sensor Linearization: Custom Callendar-Van Dusen coefficients for non-standard RTDs
  • Peer-to-Peer Mirroring: Syncs data to redundant modules via produced tags
  • Burnout Detection: 210µA current for 4-20mA transmitter diagnostics
  • High-Speed Alarming: 1ms event capture for batch process deviations
  • OPC UA Edge Gateway: Direct cloud connectivity via MQTT/Sparkplug B
