SIEMENS 6ES7321-1BL00-0AA0 SM321 DIGITAL INPUT MODULE
Product Description:
The SIEMENS 6ES7321-1BL00-0AA0 is a digital input module from the SIMATIC S7-300 series, serving as a fundamental interface between the programmable logic controller and digital field devices. This module is designed to read the ON/OFF status signals from a large number of external components such as push buttons, limit switches, proximity sensors, and relay contacts, converting these 24 V DC signals into a logical level that the S7-300 CPU can process.
This specific model is a 32-channel digital input module, offering a high density of inputs in a single standard S7-300 slot, which makes it highly space-efficient and cost-effective for applications requiring the monitoring of a vast array of two-state signals. The module is designed for reliable operation in industrial environments, featuring electrical isolation between the field-side sensor supply and the internal electronics. This isolation protects the sensitive central control system from potential voltage surges and electrical noise originating in the field. Its simple configuration and robust construction make it a versatile and reliable choice for a wide range of automation tasks in manufacturing, packaging, and assembly lines.
Technical Specifications Reference:
The SIEMENS 6ES7321-1BL00-0AA0 is a 32-channel digital input module designed for a nominal input voltage of 24 V DC. The voltage range for a signal recognized as "1" is 13 to 30 V DC, while a signal recognized as "0" is between -30 and 5 V DC. The typical input delay time is 3 ms, which can be adjusted via parameter setting to 0.1 ms, 0.5 ms, 3 ms, or 15 ms to filter out contact bounce or noise.
The module features electrical isolation in groups of 8 inputs, meaning it provides four separate isolated blocks. It requires a sensor supply from an external 24 V DC source for the field devices. The module is powered from the S7-300 backplane bus for its internal logic. It is designed for installation on a standard S7-300 DIN rail and uses a front connector for wiring. The module operates within an ambient temperature range of 0 to 60 degrees Celsius and carries standard industrial certifications such as CE and UL, ensuring compliance with safety and EMC directives.
