CMRB-11C 3AUA0000054682 | ABB I/O Board

ABB's CMRB - 11C 3AUA0000054682 is an I/O board for ACS800 series inverters with the following features and application scenarios:

Features

Electrical parameter adaptation: input voltage is 24VAC/DC, 50/60Hz, output load can reach 15A, 250VAC, which can meet the connection requirements of various electrical equipment.

Wide temperature operating range: operating temperature is - 20°C to + 55°C, storage temperature is - 40°C to + 70°C, adapting to different ambient temperature conditions, and can work stably in harsh industrial environments.

Good protection performance: The protection level is usually IP20 or IP30, which can prevent a certain degree of dust intrusion and prevent vertical dripping water from damaging the equipment.

Bus communication support: Supports logically independent dual Profibus DP buses, which can easily communicate and exchange data with other devices with Profibus DP interfaces to achieve remote monitoring and control functions.

Power redundancy and protection: It has dual power redundancy and isolation protection functions, which improves the reliability and stability of the system. When one power supply fails, the other power supply can continue to power the device. At the same time, isolation protection can prevent the power failure from affecting other circuits. In addition, it also has overheat protection and short circuit protection functions to effectively protect the output device and the entire circuit system.

Application scenarios

Industrial automation control: In various industrial automation production lines, sensors, actuators and other equipment can be connected to monitor and control the production process. For example, temperature sensors, pressure sensors, etc. are connected to collect parameters in the production process, and then the production process is adjusted by controlling actuators such as motors and valves to ensure product quality and production efficiency.

Frequency converter control system: As an important part of the ACS800 frequency converter, it is used to realize signal transmission and control between the frequency converter and external devices. It can receive instructions from the host computer or other control devices, control the operating status of the frequency converter, such as frequency setting, start and stop control, etc., and feedback the operating parameters and fault information of the frequency converter to the host computer or operator.

Electrical equipment monitoring: It can be used to monitor and protect the operating status of various electrical equipment. By collecting parameters such as current, voltage, temperature, etc. of electrical equipment, the operation status of the equipment is monitored in real time. When an abnormality occurs, an alarm signal is promptly issued and corresponding protective measures are taken, such as cutting off power supply, stopping equipment operation, etc., to prevent equipment damage and accidents.
