How Industrial Inverters Build AC From a DC Bus
Industrial inverters synthesize controllable AC from a DC bus through semiconductor switching and filtering. This guide explains H-bridges, PWM, harmonics, motor loads, protection, thermal limits,...
The BECKHOFF KM2008-0002 is a high-density Bus Terminal module featuring 64 digital outputs designed for integration within the BECKHOFF I/O system. This compact terminal module transfers binary control signals from the automation controller, providing electrically isolated switching for actuators at the process level. Featuring a pluggable wiring level, it organizes channels into eight groups of eight via multi-pin connectors.
This specific variant, the KM2008-0002, is supplied with a 1-wire connector and integrated diagnostic LEDs to indicate channel status clearly. It handles 24 V DC signals with a maximum output current of 0.5 A per channel and incorporates short-circuit proof protection. The unit communicates via the K-bus and occupies 64 bits in the process image.
