The core function of the ABB SNAT 0100-6B is as the "energy and control signal distribution center" in an inverter or motor drive system. It is responsible for precisely stepping down, regulating, and distributing the raw electrical input from the system's mains power supply, providing independent and extremely clean DC power to the core CPU control board, pulse trigger board, and sensor measurement circuitry within the drive.
This circuit board plays a crucial role in providing electrical isolation and bidirectional signal transmission between the control layer and the high-voltage power layer. Due to the extremely strong high-voltage AC electromagnetic interference inside the frequency converter (such as dv/dt noise generated by high-power IGBTs or thyristor switches), the SNAT 0100-6B integrates high-specification physical isolators and differential filter circuits.
The SNAT 0100-6B ABB PCB Control Interface Card may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The SNAT series prefix refers to a generation of hardwired computing control cards (similar to adjacent modules such as the SNAT 603 CNT or SNAT 617 CHC). These cards were widely used to connect low-voltage logic processors and high-power industrial power grid systems. Due to their age, these modules are discontinued, but Moore Automated, a professional automation supplier, continues to provide technical support.
The ABB SNAT 0100-6B primarily operates based on Multiple Switched Power Supply (SMPS) conversion technology and optoelectronic/electromagnetic coupling isolation mechanisms.
When an external AC power supply is connected to the circuit board, its internal high-frequency inverter and transformer circuitry first convert the voltage into multiple sets of high-frequency AC power. Then, through independent rectifier and linear regulator chips, multiple electrically isolated DC power supplies (e.g., ±15V, +5V, etc.) are output, thus achieving "floating ground isolation" for the power supplies of each subsystem.
In terms of signal processing, uplink speed and current sampling analog signals and downlink trigger control digital pulses are converted into optical signals or magnetically coupled differential signals during cross-border transmission across the circuit board. This completely severs the potential connection between the high-voltage and low-voltage sides, ultimately achieving closed-loop, distortion-free, high-speed interconnection for regulated energy distribution and control signals.
