High-Density Discrete Control for Compact 984 Systems

The Schneider DAP 002 serves as a robust digital output module within the Compact 984 programmable controller family. This module provides 16 discrete output channels, each delivering 24 V DC at 0.5 A for driving solenoids, relays, and indicator lights. Its sturdy housing measures 190 mm in height, 70 mm in width, and 140 mm in depth, conforming to standard rack dimensions. The total weight reaches approximately 1.1 kg, ensuring secure installation in vibration-prone environments.

Each output channel incorporates built-in short-circuit protection and over-temperature shutdown for enhanced reliability. The following table details the complete technical specifications for this digital output solution:

Channel Architecture and Load Driving Capability

The 16 output channels operate independently, allowing simultaneous control of multiple field devices. Each channel handles continuous currents up to 0.5 A, with a total module capacity of 8 A. This current rating supports direct connection of small relays, pilot lamps, and pneumatic solenoid valves. The module also tolerates inductive loads with integrated flyback diodes for arc suppression.

Protection Mechanisms and Diagnostic Feedback

Built-in short-circuit protection automatically disables any channel experiencing an overcurrent event. Over-temperature shutdown safeguards the module during sustained high-load conditions or inadequate ventilation. Diagnostic LEDs provide immediate visual status for each channel, simplifying field troubleshooting. Maintenance teams can therefore identify faulty outputs without external test equipment.

Power Architecture and System Integration

The DAP 002 requires both 5 V DC logic power from the backplane and 24 V DC field power from an external supply. This separated power architecture isolates control circuits from load transients. Operating temperatures from 0°C to +60°C cover standard industrial environments without derating output current. The storage temperature range from -40°C to +85°C ensures product integrity during transportation. A 1500 V AC isolation barrier protects the logic side from field-side faults and electrical noise.
