Honeywell|MU-GAIH22| Field Termination Assembly
Honeywell MU-GAIH22 Description
The Honeywell MU-GAIH22 is a galvanically isolated High Level Analog Input (HLAI) Field Termination Assembly (FTA) designed for interfacing with process control systems in hazardous environments.
Features
- Supports high-level analog input signals
- Galvanic isolation for enhanced safety
- Compatible with redundant Input/Output Processors (IOPs)
- Suitable for hazardous area applications
Technical Specifications
General
- Input Channels: 16 high-level analog inputs
- Signal Type: 4-20 mA (requires 250 ohm resistor for 1-5 V conversion)
- Isolation: 250 Vac between safe and hazardous sides
- Safety Parameters: 28 V max, 300 ohms, 93 mA max per channel
Connectors
- IOP Interface: Two 50-pin connectors for redundant IOPs via MU-KFTAxx cables
- Auxiliary Output: 50-pin connector for 1-5 V or 4-20 mA signals
- Field Wiring: Compression or crimp-type terminal connectors
Electrical
- Current Consumption: 0.75 A at 24 Vdc (typical)
- Power Dissipation: 12 W (all channels active)
Environmental
- Ambient Temperature: -40°C to +70°C (operating)
- Humidity: 5% to 95% non-condensing
Indicators
- Primary IOP Control: Green LED for active IOP
- Module Status: Green LED per galvanic isolation module
Safety and Compliance
- Certifications: CE compliant, suitable for Division 2 hazardous locations
- Subsystem Impedance: 250 ohms or less for 4-20 mA signals
