Information About 1746-INT4
The 1746-INT4 is part of the Allen-Bradley SLC 500 series and serves as a dedicated analog input module for thermocouples and low-voltage mV devices. Its design includes four isolated channels, each electrically separated from one another and from the backplane, enabling reliable measurement in electrically noisy installations. The module supports multiple thermocouple standards-including types C, D, J, K, T, E, R, S, B, and N—along with selectable millivolt ranges to accommodate sensor transducers. With digital filtering, open-circuit detection, and sigma-delta ADC conversion, it ensures stable measurement performance within process control and temperature monitoring systems.
Key Features:
- Four isolated input channels: Individually isolated from each other and the backplane.
- Thermocouple compatibility: Supports types C, D, J, K, T, E, R, S, B, and N.
- mV signal support: Accepts –50…50 mV and –100…100 mV DC ranges.
- 16-bit resolution: Provides precise digital representation of analog signals.
- Cold junction compensation: ±1.5°C accuracy within 0–70°C operating range.
- Sigma-delta ADC conversion: Enhances measurement stability and noise immunity.
- Open-circuit detection: Configurable upscale, downscale, or zero indication.
- Low-pass digital filtering: 8 Hz channel bandwidth for smoother analog input.
- Step response performance: 100 ms input and 2.5 ms output response.
- LED channel indicators: Visual status monitoring for each input channel.
- Wide operating temperature: Suitable for 0–60°C industrial environments.
The 1746-INT4 delivers the reliability and precision required for accurate thermocouple and millivolt measurement within SLC 500 automation systems.
