Description
1. Product Description
GE H201Ci-1 (Hydran 201Ci-1) is a single-channel controller designed for the Hydran 201i gas monitoring system, specializing in precise gas concentration measurement and control. As a critical component for industrial safety and condition monitoring, H201Ci-1 integrates with the Hydran 201Ti intelligent transmitter to deliver real-time data on gas levels (e.g., moisture in transformer oil). It features a NEMA 4X-rated heated enclosure for harsh environments, isolated 4–20 mA analog outputs (0–2000 ppm range), and dual alarm thresholds (high/high-high) for safety-critical applications. With support for power failure and communication loss alarms, H201Ci-1 ensures reliable operation in energy, manufacturing, and utilities sectors.

3. Advantages and Features
- Precision Monitoring: ±2% accuracy ensures reliable gas concentration analysis for predictive maintenance.
- Safety Redundancy: Fail-safe design with alarm-triggered analog output reset (0 mA) and display blanking during faults.
- Environmental Resilience: NEMA 4X enclosure and wide temperature range (-40°C to 85°C) suit extreme industrial settings.
- Easy Integration: Seamless pairing with Hydran 201Ti transmitters via dedicated communication protocols.
- Modular Design: Single-circuit board for simplified maintenance and firmware updates.
4. Application Areas and Case Studies
Industries: Power generation (transformer monitoring), oil & gas (condition-based maintenance), manufacturing (process safety).
Case Study: A utility company deployed H201Ci-1 in 50+ transformers to monitor moisture levels. The system detected early-stage insulation degradation in three units, enabling proactive repairs and avoiding $2M in potential downtime. Integration with SCADA reduced manual inspections by 40%.

6. Selection Recommendations
- Application Needs: Choose for single-channel gas monitoring (e.g., moisture, hydrogen) in critical assets.
- Voltage Compatibility: Verify 24 VDC power supply availability.
- Enclosure Requirements: Opt for NEMA 4X (heated) for outdoor/harsh environments.
- Integration: Ensure compatibility with Hydran 201Ti transmitters (via GE’s proprietary communication link).
7. Precautions
- Installation: Follow NEMA 4X enclosure mounting guidelines (IP66/IP67 equivalent).
- Calibration: Schedule annual calibration using GE’s certified tools (e.g., Hydran 201i software).
- Power Surges: Use surge protection devices (SPD) to prevent voltage spikes.
- Firmware: Update regularly via GE’s secure portal to address security patches and feature enhancements.
