Product description

The Siemens SIMATIC S7-300 SM 323 (Part Number: 6ES7323-1BH81-0AA0) is a digital I/O module designed for the SIMATIC S7-300 programmable logic controller series. This module provides 8 optically isolated digital inputs (DI) and 8 optically isolated digital outputs (DO), all rated for 24V DC. Each output can handle a current of 0.5A, with a total current consumption of 2A for the module. It features a 20-pin connector for connections and is designed for an expanded temperature range, making it suitable for challenging environments.

This digital module is essential for interfacing discrete signals with the S7-300 PLC. Applications include controlling actuators like solenoid valves and contactors (outputs), and receiving signals from pushbuttons, limit switches, and sensors (inputs). It's widely used in manufacturing automation, process control, material handling, and building automation systems requiring reliable digital I/O.
