Description
GE Fanuc 8810-HI-TX-01 High-Current Transmitter Module
The 8810-HI-TX-01 is a 4-20mA analog output module designed for GE Fanuc PACSystems RX3i/RX7i platforms, engineered to deliver precise current signals for industrial automation, process control, and energy management. With 12-bit resolution and ±0.05% accuracy, this module supports high-current applications (up to 250mA) in harsh environments, ensuring reliable control of valves, actuators, and pumps in oil refineries, power plants, and water treatment facilities.
1. Product Overview
The 8810-HI-TX-01 bridges the gap between GE’s PACSystems controllers and field devices, converting digital commands into analog current signals. Its dual-channel design allows independent control of two outputs, while short-circuit protection and overload immunity safeguard against equipment damage. The module’s -40°C to +70°C operating range and IP20-rated enclosure make it suitable for extreme conditions, and its hot-swap capability minimizes downtime during maintenance.

3. Advantages and Features
- High-Current Capability: Supports 250mA output, 2.5x higher than standard modules, ideal for heavy-duty actuators in oil pipelines.
- Precision Control: ±0.05% accuracy reduces process variability by 18% in chemical mixing systems (case study: U.S. plant cut product waste by $500K/year).
- Fault Tolerance: Auto-recovery from short circuits (50ms reset) eliminates manual intervention, critical for offshore platforms.
- Energy Efficiency: Low power consumption (500mA idle) cuts energy costs by 22% compared to legacy modules.
4. Application Areas and Case Studies
- Oil & Gas: Controls hydraulic valves in subsea wellheads, maintaining ±0.1% pressure stability (Norwegian offshore platform: 0 failures in 3 years).
- Power Generation: Adjusts steam turbine fuel injectors in combined-cycle plants, optimizing efficiency by 5% (Middle Eastern plant saved $2M/year).
- Water Treatment: Drives chemical dosing pumps in wastewater facilities, achieving ±0.5% flow rate accuracy (German utility cut reagent usage by 20%).
Case Study: A European automotive plant deployed 8810-HI-TX-01 to control robotic welding arms. The module’s high-current stability reduced weld defects by 35%, saving €1.2M annually.
5. Competitor Comparison
- Current Capacity: 250mA vs. 100mA in comparable modules, enabling direct actuation without amplifiers.
- Accuracy: ±0.05% vs. ±0.1% in legacy models, critical for pharmaceutical dosing applications.
- Temperature Range: Operates at -40°C vs. -20°C industry standard, ideal for Arctic oilfields.

6. Selection Recommendations
- Current Requirements: Use 8810-HI-TX-01 for high-current loads (>100mA); downsize to 8810-LV-TX-01 (100mA) for low-power systems.
- Redundancy: Pair with 8810-HI-TX-01-EC for dual-channel redundancy in safety-critical processes.
- Environment: Opt for 8810-HI-TX-01-H (IP65-rated) for outdoor/washdown areas (e.g., food processing).
7. Precautions
- Wiring: Use AWG 18–22 shielded cables; terminate with ferrules to prevent short circuits.
- Load Impedance: Ensure total load ≤500Ω to avoid voltage drop and signal degradation.
- Calibration: Annual factory calibration via GE’s PAC Manager maintains long-term accuracy.
- Software Configuration: Enable current limiting in Proficy for inductive loads to prevent overheating.
