The ABB 1MRK000161-AAr01 serves as the primary 1MRK000161 Control Board utilized to execute analog signal acquisition, digital I/O processing, and internal control logic functions across ABB automation system platforms. The board integrates high-resolution analog input channels, opto-isolated digital interfaces, onboard DDR3 memory, and reinforced electrical isolation between field and logic circuits.

Model Identification

No official suffix matrix or option code breakdown is specified within the available product data. The supplied configuration corresponds to ABB model 1MRK000161-AAr01.

Hardware Specifications

I/O Density and Signal Processing Architecture

The board provides a combination of 12 analog input channels and 24 digital I/O channels within a single hardware assembly. Analog channels support both voltage and current signal acquisition using 16-bit conversion resolution, while opto-isolated digital interfaces provide electrical separation between field wiring and internal processing circuitry.

The 3000 V AC isolation barrier between I/O circuits and logic sections assists in reducing the transfer of electrical disturbances originating from field devices or external control wiring.
