Product Description:

The MCMAEB-0 by B&R Automation is a versatile MINI digital mixed module that combines 16 digital inputs and 16 transistor outputs. Its 16 channels for input each operate at a nominal voltage of 24 VDC. Its capacity for signals from up to 16 different devices or sensors, making it suited for a wide range of applications including complex systems that require processing of multiple signals at the same time. The module processes signals at a rate of 5 milliseconds, ensuring quick response times for efficient performance. The module delivers a seamless user experience with a 16 LED Status display that provides quick visual feedback on the status of the module.

This digital module is equipped with 16 transistor outputs that are designed to run on a 24 VDC power supply. These outputs utilize a sink layout that connects to the ground or common side of the power supply, providing a path for current to return to the ground. This allows for efficient control of multiple devices with a single module. The module is designed to handle output currents of up to 0.5 A for each of its 16 transistor outputs. It supports a combined output current of up to 8 A across all 16 transistor outputs, allowing for effective control of connected equipment. The module comes with robust short circuit and overvoltage protection to ensure safe operation.

The MCMAEB-0 module is built to integrate seamlessly with existing systems for enhanced system efficiency. It interfaces easily with various digital I/O configurations, providing users with versatility in setting up their application design. For optimal performance, this module should be operated within a temperature range of 0 to 50 °C.
