Siemens 6ES7326-1BK00-0AB0 Programmable Logic Controller Module

Siemens 6ES7326-1BK00-0AB0 is a fail-safe digital input module for the SIMATIC S7-300F family, delivering 24 channels that accept 24 V DC signals. Built for safety-related automation tasks, it is used to monitor sensors, safety interlocks, and other 24 V DC devices in industrial control systems requiring fail-safe operation. Identified as 6ES7326-1BK00-0AB0 from the Siemens SM326 fail-safe input module family, it provides 24 x DC 24 V inputs and integrates with the S7-300F safety architecture to enable diagnostic reporting to the safety CPU. Typical applications include packaging lines, material handling, and process automation where reliable 24 V DC input signaling is essential to safety logic. In addition to basic input scanning, the module supports diagnostic interrupts to help operators detect and respond to sensor faults quickly.
