Working Principle: The D4-32TD2 receives logic signals from the DL405 PLC system via the backplane. Each of the 32 output channels switches a DC load (12-24 VDC) using transistor technology. The outputs are sourcing (PNP) type, meaning they supply positive voltage to the load when activated. The module provides faster switching speeds compared to relay outputs and eliminates the mechanical wear associated with relays.
