Industrial D3-05B-1 Auxiliary Power Supply Module

The D3-05B-1 DirectLogic 5-slot DL305 expansion base is an auxiliary power supply module for AutomationDirect's DL305 PLC system, designed to mount in a panel and support up to five I/O slots. It requires external 110–220 VAC input to operate and includes a 24 VDC auxiliary power supply rated at 100 mA to power peripheral devices from the same base. The unit provides run signaling via a Run relay rated for 250 VAC at 4 A (resistive load) and uses 2 A (250 VAC) non-replaceable fuses on the base; the total current for the D3-05B-1 must not exceed 2.3 A. Dimensions are 11.42 inches wide by 4.85 inches high and 4.41 inches deep, making it suitable for standard panel installations in industrial control panels. This 5-slot base integrates with DL305 CPUs and I/O modules to deliver power distribution and essential control signaling for compact, rack-mounted automation setups.
