Siemens Modules 6ES7326-1RF00-0AB0

The Siemens 6ES7326-1RF00-0AB0 module is a fail-safe digital input module for the SIMATIC S7-300 system, designed for safety-critical applications. 

Specification:

• Module Type: It is an SM 326 digital input module.
• Functional Safety: This module is a fail-safe component for use in safety-oriented automation systems, meeting requirements up to Category 4 (EN 954-1), SIL 3 (IEC 61508), and PL e (ISO 13849).
• Input Channels: The module features 8 digital inputs.
• Input Type: The inputs are designed for NAMUR sensors (according to EN 60947-5-6), which are commonly used in hazardous environments.
• Ex(i) Characteristics: It has intrinsically safe (Ex(i)) characteristics, making it suitable for use in potentially explosive atmospheres, providing Ex(i) protection.
• Supply Voltage: The rated supply voltage (DC) is 24 V.
• Connection: It connects via a single 40-pin connector. 

The module’s primary function is to reliably detect digital signals from sensors in the field, particularly those located in hazardous zones, and transmit this information to the SIMATIC S7-300 controller for safety-related processing.
