SM 323 - Digital in-/output
16x DI
16x DO
DC 24 V
1 A
For 40 pole front connector

Product Description:

The SM 323 (323-1BL00) is a powerful digital I/O module specifically designed for industrial automation systems. It offers 16 digital inputs and 16 digital outputs operating at 24 V DC with a maximum output current of 1 A. The module is compatible with a 40-pin front connector, providing flexible options for various system configurations. The inputs support both shielded and unshielded cables with lengths of up to 1000 m or 600 m respectively, ensuring high-quality signal processing in line with IEC 61131-2 standards.

The digital outputs of the SM 323 are sourcing-based and feature short-circuit protection along with electronic overcurrent shutdown. They also support parallel switching for redundant load control. Additionally, the module provides a green LED status indicator for each channel and offers comprehensive diagnostic capabilities, including group error indication via a red SF LED.

The robust housing, made from PPE material, ensures durability, while its compact design allows for easy installation on the Rail System 300. With UL and KC certifications, the SM 323 meets international safety standards. This module is ideal for applications that require reliable and flexible control of digital inputs and outputs, offering high operational safety through channel isolation and backplane bus insulation.
