ABB MM21 MM 21 Module Advanced Industrial Control Solution
The ABB MM21 Module is a versatile input/output module designed for industrial automation systems. Key specifications include: 24V DC input, 16 digital inputs, and 16 digital outputs, with a maximum switching frequency of 1 kHz. It is typically used in process control, manufacturing, and energy management applications. Compared to the ABB DO572, the MM21 offers more I/O channels but a lower switching frequency. Unlike the AI830, which focuses on analog signals, the MM21 is optimized for digital control, making it suitable for discrete operations.
