Description
Product Overview
The B&R 7AT664.70 is a screw‑in analog input module within the B&R 2003 I/O system, specially designed for thermocouple temperature measurementB& R Indus…. It provides four independent input channels to collect millivolt‑level signals from thermocouple sensors, converts analog thermal‑voltage values into high‑precision 16‑bit digital readings and transmits temperature data to the automation CPU. This module needs external terminal block 7TB712.9 /7TB712.91 for field wiring connectionB& R Indus…. Built‑in cold‑junction compensation ensures accurate temperature acquisition, widely used for temperature monitoring and closed‑loop thermal control on machinery and process‑automation retrofit projects.
