6ES7321-1BL00-0AA0

Siemens' 6ES7321-1BL00-0AA0 is an efficient input module designed for the SIMATIC series. This unit is equipped with 32 inputs, each functioning at a voltage rating of 24 V DC. The module effectively draws a current of 15 mA when operating at 5 V DC, ensuring minimal power consumption relative to its capabilities. The device can handle input signals in both sinking and sourcing configurations, enhancing versatility in application usage.

With a signal delay of 3.0 ms, the module is capable of providing timely input signals to connected systems. The response time ranges from 0.1 to 3 ms, which supports various operational requirements. This module maintains an isolation voltage rating of 500 V DC, adding to its robustness and reliability. Positions of inputs, status indicators, and connectors can be easily accessed via screw terminals or push-in connectors, simplifying wiring interfaces.

Constructed in a compact format, the module fits seamlessly in rack-mounted applications. It measures 125 mm in height, 40 mm in width, and 120 mm in depth, while weighing 260 g, making it suitable for space-constrained installations. Typical power dissipation is recorded at 1.3 W, contributing to its efficient operation. With an IP20 protection rating, this module offers solid resistance against the ingress of solid objects, making it ideal for less hostile environments.
