Allen Bradley 1769sc-IT6I Thermocouple Input Module

Product Overview

The Allen Bradley 1769sc-IT6I is a high-performance Thermocouple Input Module designed for the CompactLogix system. Manufactured by Spectrum Controls, this module features six isolated input channels that support a wide range of thermocouple types (J, K, T, E, R, B, S, N, C, L) as well as millivolt signals (±50 mV, ±100 mV). Ideal for use in temperature measurement and transducer interface, it provides precise analog data conversion with high isolation standards.

Key Features

6 Isolated Channels: Supports both thermocouple and millivolt inputs, allowing flexible integration with various sensor types.
High Isolation: Ensures 125 VAC channel-to-channel isolation, with additional isolation between field wiring and backplane, and field wiring and chassis ground.
Temperature Range: Operates within 0 °C to 60 °C (32 °F to 140 °F), making it suitable for various industrial environments.
Resolution: Offers a 16-bit resolution for accurate measurement.
Configurable Parameters: Features adjustable filter times and update times for fine-tuned performance.
Overvoltage Protection: Includes ±35 VDC continuous overvoltage protection, enhancing durability and safety.
