PLCs, Power Supplies & Others

The Schneider 140DDO84300 delivers rugged discrete switching capacity for Modicon Quantum control systems. This 16-channel source output module operates across a wide 10 to 60 VDC range for diverse industrial load control.

Key Technical Specifications

Wide-Range Output Capability

The Schneider 140DDO84300 accepts field supply voltages from 10 to 60 VDC, accommodating worldwide control voltages without modification. This wide input range eliminates the need for different modules for 12V, 24V, and 48V applications.

Each channel delivers up to 0.5 A continuous current with surge capability for incandescent lamp loads. The module maintains full output capacity across the entire voltage range without derating.

Channel Grouping and Power Distribution

This discrete output module arranges its 16 channels into two independent groups of eight. Each group requires an external DC power supply connected to the common terminals, allowing mixed voltages within a single module.

Engineers can power Group A from a 24 VDC supply for solenoid valves while powering Group B from 48 VDC for motor contactors. This flexible architecture reduces total I/O count in mixed-voltage control panels.

Positive Logic Source Outputs

The 140DDO84300 employs positive logic source outputs, switching the positive side of the DC supply to the load. This configuration suits industrial applications in North America and follows standard sourcing conventions for programmable controllers.

Each output utilizes a power MOSFET switching element with zero-voltage turn-on characteristics. This solid-state design provides wear-free operation with virtually unlimited switching cycles.

Mechanical Design and Form Factor

Weighing approximately 0.32 kg, this discrete output module occupies a single slot in Modicon Quantum racks. Its dimensions of 130 mm x 40 mm x 100 mm enable high-density I/O configurations within space-constrained enclosures.

The module faceplate features 16 green LED indicators, one per output channel. Each LED illuminates when the corresponding output energizes, providing immediate operational status verification.

System Integration with Modicon Quantum

Schneider engineered the 140DDO84300 exclusively for the Modicon Quantum automation platform. The module connects directly to the Quantum backplane through the standard 96-pin connector, requiring no special adapters.

The module communicates with Quantum CPUs including 140CPU31110, 140CPU43412, and 140CPU65150 models. Unity Pro and Concept software provide complete configuration access for output state forcing and failure mode presets.

Output Protection and Diagnostics

Each of the 16 output channels includes short-circuit and overload protection with automatic thermal shutdown. The module detects fault conditions and disables the affected channel while maintaining normal operation on remaining outputs.

An overtemperature condition on any channel triggers system diagnostics without controller shutdown. This fault tolerance maintains critical process outputs while alerting maintenance personnel to developing issues.

Bus Current and Power Consumption

The 140DDO84300 draws only 160 mA from the 5 VDC backplane bus, minimizing power supply loading in densely populated racks. This efficient design allows maximum I/O counts within standard Quantum power supply capacity.

External field power does not pass through the backplane connector. Load current flows entirely through the field wiring terminals, separating logic power from output power for enhanced noise immunity.

Leakage Current and Off-State Performance

Maximum leakage current measures just 1 mA at 60 VDC, preventing nuisance operation of sensitive loads. This low off-state current proves essential when driving solid-state relays, small pilot lights, or PLC inputs from other systems.

The module guarantees output off-state up to 72 VDC continuous, providing safety margin for transient voltages on industrial power networks. This robust design withstands common power line disturbances without false triggering.

Application Versatility

Manufacturing facilities deploy the Schneider 140DDO84300 across numerous discrete control applications. Typical implementations include solenoid valve actuation, motor starter control, indicator lamp driving, and interposing relay operation.

The wide 10-60 VDC operating range simplifies global machine designs. Equipment destined for different regions requires only field supply adjustment rather than module replacement.
