Key Features

1. 16-Channel High-Density Temperature Monitoring

• Provides 16 independent thermocouple input channels, supporting 10 common thermocouple types (J, K, N, T, E, R, S, B, C, X) for versatile temperature measurement across diverse industrial processes.
• High channel density minimizes rack space usage and reduces wiring costs in multi-point monitoring applications.

2. Precision Measurement with 0.5° Resolution

• Delivers 0.5°C or 0.5°F configurable resolution, ensuring accurate and consistent temperature data for critical control loops and quality assurance.
• Factory-calibrated accuracy of ±0.5°C (typical for J/K/N/T types) eliminates the need for on-site calibration.

3. Advanced Fault Detection & Diagnostics

• Integrated open-circuit detection triggers a discrete alarm bit (%I) and drives the analog input register (%AI) to maximum value when a sensor wire breaks, enabling immediate fault identification.
• Overvoltage protection safeguards the module from ±35 VDC input spikes, ensuring reliability in electrically noisy environments.

4. Superior Noise Immunity & Signal Integrity

• 20 MΩ high input impedance minimizes loading on thermocouple sensors, preserving weak millivolt-level signal integrity.

• 100 dB common mode rejection ratio (CMRR) eliminates ground loop interference and electrical noise, ensuring stable readings in harsh industrial environments.

5. Compact & User-Friendly Design

• Single-slot form factor with a 32-position removable terminal block simplifies wiring and maintenance.
• Direct compatibility with GE Series 90-30 PLCs requires no external adapters or signal conditioners, reducing system complexity.
• LED status indicators provide visual confirmation of module power and channel activity for quick troubleshooting.

Applications

• Process Manufacturing: Chemical, pharmaceutical, and food & beverage plants for reactor, furnace, and sterilization temperature monitoring.
• Power Generation: Gas/steam turbines, power boilers, and heat recovery steam generators (HRSGs) for combustion and exhaust temperature measurement.
• Oil & Gas: Refineries, petrochemical facilities, and pipeline operations for process heater, crude oil, and natural gas temperature monitoring.
• Metallurgy & Heavy Industry: Steel mills, aluminum smelters, and cement plants for furnace, kiln, and molten metal temperature control.
• HVAC & Building Automation: Large commercial facilities and data centers for environmental and equipment temperature monitoring.
