Allen-Bradley 1762-IT4 | MicroLogix 1200 Thermocouple Input Module

Product Overview

The Allen-Bradley 1762-IT4 is an analog input module designed for the MicroLogix 1200 system. This compact unit supports four thermocouple or millivolt inputs and includes a Cold Junction Compensator (CJC) for improved measurement accuracy.

It is compatible with multiple thermocouple types such as J, K, T, E, R, S, B, N, and C, allowing flexible integration across different temperature sensing applications. In addition, it can accept ±50 mV and ±100 mV analog signals, making it ideal for precise transducer monitoring.

Using a Delta-Sigma conversion method, the 1762-IT4 achieves a 15-bit plus sign resolution. Each input channel has configurable digital filters at selectable frequencies ranging from 10 Hz to 1 kHz, ensuring stable readings even in electrically noisy environments.

Key Specifications of Allen-Bradley 1762-IT4

Performance and Application

The Allen-Bradley 1762-IT4 supports a wide measurement range from -210 °C to 2315 °C (-346 °F to 4199 °F) depending on the thermocouple type. Its auto-calibration process during power-up ensures accuracy, while programmable calibration options provide additional flexibility.

For mV signal wiring, the recommended cable is Belden 8761, ensuring precise data transfer. The module connects directly to the MicroLogix 1200 controller or adjacent I/O modules, secured with DIN rail mounting and a snap-on locking mechanism.

Its rugged design allows installation in demanding environments with vibration levels up to 5 g and operational shocks of 30 g, making it highly dependable for industrial automation systems.

Safety and Installation Notes

Installers must use wiring appropriate for the selected thermocouple or millivolt sensor. Always ensure the system operates within the specified power supply range to avoid errors. Proper grounding and stable mounting help maintain measurement accuracy and extend service life.
