Schneider 140DDO35300C Output Module

Schneider Electric 140DDO35300C Modicon Discrete Output Module

Product Introduction

The Schneider Electric 140DDO35300C output module delivers robust discrete control for the Modicon Quantum automation platform. This module manages 32 distinct output points organized into 4 separate groups. Therefore, it offers flexible configuration for various field devices. Each group contains 8 channels and operates using positive source logic. Consequently, this design simplifies wiring and troubleshooting for engineers. Additionally, the 140DDO35300C requires only 2 output words for addressing. This feature reduces the memory footprint in your control program. Meanwhile, its compact standard format fits easily into existing Quantum racks. For instance, you can deploy this module in manufacturing, process, or hybrid applications.

Technical Specifications

The Schneider Electric 140DDO35300C operates at a nominal discrete output voltage of 24V DC. Its output voltage limits range from 19.2V to 30V DC, providing flexibility for different power supplies. The absolute maximum output reaches 56V for a 1.3-second decaying pulse. Moreover, the module supports a maximum load current of 16 Amps per module. However, each group limits the current to 4 Amps for balanced load distribution. Furthermore, the maximum voltage drop measures less than 0.4V at 0.5A, ensuring efficient power delivery. The surge current capability is 5A for 0.0005 seconds, handling brief inrush events effectively.

Response times are critical for high-speed applications. Specifically, the 140DDO35300C achieves a response time of ≤1 ms for both state 0-to-1 and 1-to-0 transitions. Additionally, the maximum leakage current is only 0.4 mA at 30V, minimizing unwanted current draw. For inductive loads, the load inductance formula is Inductance(H) = 0.5/((current(A))² x (switching frequency(Hz))) at 50 Hz. This calculation helps you select appropriate loads. Besides that, the module provides clear fault indication for loss of field power or blown fuses. Each point has an associated 3A fuse, while each group has a 5A fuse.

Isolation and Protection

The Schneider Electric 140DDO35300C offers robust isolation for safety and signal integrity. Isolation between channels and the bus is 1780 Vrms DC for 1 minute. Meanwhile, isolation between groups is 500 Vrms DC for 1 minute. This high isolation prevents cross-channel interference. Furthermore, protection includes an internal output protection fuse of 5A per group. Power dissipation is calculated as 1.75W + (0.4V x total module load current). Therefore, you can estimate heat generation for your cabinet design. The module also features conformal coating (Humiseal 1A33) for protection against moisture and contaminants.

Environmental and Compliance

The 140DDO35300C operates in ambient temperatures from 32°F to 140°F (0°C to 60°C). For storage, it withstands temperatures from -40°F to 185°F (-40°C to 85°C). Additionally, it handles relative humidity up to 95% without condensation. The operating altitude reaches up to 5000 metres (16,404 feet). This module carries multiple certifications, including GL, RINA, BV, GOST, DNV, FM Class 1 Division 2, C-tick, RMRS, and ABS. It also meets CSA C22.2 No 142 and UL 508 standards. Furthermore, it resists electrostatic discharge up to 4kV contact and 8kV on air per IEC 801-2. Electromagnetic field resistance is 9.1V/m (10V/m) over 80–2000 MHz per IEC 801-3.

Installation and Addressing

Installing the Schneider Electric 140DDO35300C is straightforward. The module uses a standard Quantum format and fits directly into the backplane. Addressing requires only 2 output words, simplifying configuration in your programming software. Local signalling includes one green LED for bus communication active. Additionally, one red LED indicates an external fault. Moreover, 32 green LEDs show the status of each output point. This visual feedback aids in rapid troubleshooting. For wiring, observe the positive source logic—the outputs source current to the load.
