Allen-Bradley 1746-INT4 Module

1. 4 Individually Isolated Channels: Each channel is electrically isolated to prevent cross-talk, voltage spikes, and ground loops, ensuring precise signal integrity for critical temperature and mV measurements.
2. Multi-Thermocouple Compatibility: Supports 10 thermocouple types (B, C, D, E, J, K, N, R, S, T) to match diverse industrial temperature sensing needs, from cryogenic to high-temperature processes.
3. Millivolt Input Flexibility: Accepts ±50 mV and ±100 mV DC ranges for direct connection to low-voltage transducers, eliminating the need for external signal conditioning.
4. Integrated Cold Junction Compensation (CJC): Built-in CJC ensures accurate temperature readings by automatically compensating for ambient terminal temperature variations, critical for thermocouple-based measurements.

Application Areas:

1. Chemical and petrochemical process temperature control
2. Metal heat treatment and forging operations
3. Food and beverage pasteurization/sterilization monitoring
4. Pharmaceutical production (temperature-sensitive processes)
5. Power generation equipment (boiler, turbine temperature sensing)
6. Automotive manufacturing (paint curing, assembly line heating)
7. Low-voltage transducer signal acquisition (pressure, strain, flow)
