PLCs, Power Supplies & Others

The Honeywell MC-GAIH22 is a precision analog input module engineered for Honeywell’s Quality Control System (QCS) product suite. This module captures critical process measurements with exceptional accuracy and repeatability. It delivers real-time visibility into manufacturing parameters for pulp, paper, plastics, rubber, nonwoven, and aluminum sheet applications.

Key Technical Specifications

Precision Measurement for Process Visibility

The MC-GAIH22 delivers 16-bit resolution across eight differential input channels. You achieve 0.05 percent accuracy for critical basis weight, moisture, and caliper measurements. This precision enables tight quality control across continuous web processes. Consequently, you reduce off-spec production and material waste.

Real-Time Data Acquisition at 250 Samples per Second

Each channel samples at 250 times per second for true real-time process visibility. You therefore detect rapid variations in sheet properties immediately. The MC-GAIH22 captures transient events that slower modules miss entirely. This speed supports advanced model-based control strategies.

Flexible Input Configuration for Multiple Sensor Types

You configure each channel independently for voltage or current signals. The module accepts ±10 V, 0–10 V, and 4–20 mA inputs without external signal conditioners. Voltage inputs present greater than 10 megohms impedance for minimal sensor loading. Current inputs utilize precision 250 ohm burden resistors.

Superior Noise Rejection for Industrial Environments

The MC-GAIH22 provides 90 dB common mode rejection across all channels. Normal mode rejection reaches 60 dB at 50 Hz and 60 Hz power line frequencies. You therefore obtain clean signals despite AC motor drives and switching power supplies. This noise immunity proves essential for accurate scanning sensor systems.

Predictive Maintenance Through Continuous Data Collection

This module feeds high-resolution process data directly to Honeywell QCS analytics platforms. You trend sensor performance over time to predict impending failures. The MC-GAIH22 supports condition-based maintenance rather than scheduled replacements. This approach minimizes unplanned downtime and extends sensor life.

Alarm and Notification Integration

Each input channel features independently configurable high and low alarm thresholds. You receive immediate notification when process variables deviate from specification. The MC-GAIH22 communicates alarms through the QCS network to operator stations. This rapid alerting enables corrective action before product becomes non-compliant.

Scalable Architecture for Manufacturing Lines

You install multiple MC-GAIH22 modules within a single QCS rack assembly. The system scales from single-sensor applications to complete multi-scanner measurement frames. Each module operates independently while sharing common power and communication backplanes. This flexibility accommodates both machine direction and cross-direction measurement requirements.

Industrial-Grade Environmental Specifications

The MC-GAIH22 operates continuously from 0 °C to +60 °C ambient temperature. You therefore install it in non-conditioned control cabinets adjacent to the process line. Non-condensing humidity tolerance reaches 95 percent. The module withstands vibration typical of paper machine and rolling mill environments.

Energy Storage and Long-Term Reliability

This module contains no internal batteries or supercapacitors. You eliminate periodic maintenance cycles entirely. Solid-state components provide decades of reliable service life. The MC-GAIH22 therefore delivers exceptional total cost of ownership over its operational lifetime.

User-Centered Design for Simplified Maintenance

The module features clearly labeled terminal connections and diagnostic LED indicators. You verify operational status at a glance without external test equipment. Removable connectors permit off-line wiring harness assembly. Consequently, you replace the MC-GAIH22 in minutes without disturbing field wiring.
