ABB DSDX452 Mixed Digital I/O Module
The ABB DSDX452 is a combined digital input and output module designed for industrial automation and control system architectures. It integrates 20 digital input channels for field signal acquisition alongside 12 fully isolated digital relay outputs, enabling controllers to monitor process conditions and switch external loads.
I/O Configuration and Relay Switching
The module provides high-density discrete interfacing within a single unit. Its 12 relay output channels support a switching voltage range of 24 to 240 V AC/DC to drive auxiliary relays, contactors, lamps, or solenoid valves. Standard versions recommend a minimum load of 2.5 VA (100 mA at 24 V DC), while the DSDX452L variant provides low-voltage relay contacts designed for smaller signal-level loads (maximum 200 mA, minimum 5 mA or 0.05 VA).
