Schneider Electric 140DDI35310 Discrete Input Module

The Schneider Electric 140DDI35310 is a low voltage DC discrete input module for the Modicon Quantum platform. Specifically, this module provides 32 negative logic (source) inputs. You can therefore connect 24V DC field devices directly to your Quantum PLC. Arranged in 4 groups of 8 channels each, these inputs simplify field wiring. Moreover, addressing requires only 2 input words for all 32 points.

Technical Specifications of the 140DDI35310

Regarding input voltage, the Schneider Electric 140DDI35310 operates at 24V DC. The input voltage limits range from 19.2 to 30V DC. For proper negative logic operation, voltage state 1 is guaranteed between -30V and -15V DC. Meanwhile, voltage state 0 is guaranteed between -5V and 0V DC. Input impedance is 2400 Ohms.

Current Requirements

For state 1, the guaranteed current is at least 2.5 mA at Us = -14V. For state 0, the guaranteed current is ≤ 0.5 mA. Maximum leakage current is 200 mA at Us = 5.5V and Uin = 4V. These ratings ensure reliable signal detection from field devices.

Response Time and Protection

Response time measures ≤ 1 ms from state 0 to state 1. Similarly, response time is ≤ 1 ms from state 1 to state 0. For protection, the Schneider Electric 140DDI35310 uses resistor-limited input protection. The absolute maximum input is 30V continuous. Additionally, a decaying 50V pulse for 1 ms is tolerated.

Power Dissipation and Isolation

Power dissipation follows the formula 1.5W + (0.26 x number of points on). Isolation between group and bus is rated at 1780 Vrms for 1 minute. Isolation between groups is 500 Vrms for 1 minute. Bus current requirement is 330 mA for reliable operation.

Local Signaling

Several LED indicators are provided on this module. One green LED shows that bus communication is present (Active). A single red LED indicates an external fault detected (F). Additionally, 32 green LEDs show the status of each input point. CE marking is present for European compliance.

Certifications and Standards

Multiple certifications are held by the Schneider Electric 140DDI35310. These include RINA, GOST, FM Class 1 Division 2, C-tick, and RMRS. Furthermore, the module complies with UL 508 and CSA C22.2 No 142 standards.

Environmental Specifications

For electrostatic discharge, the module handles 4 kV contact per IEC 801-2. It also withstands 8 kV on air per the same standard. Regarding electromagnetic fields, it resists 10 V/m from 80 to 2000 MHz per IEC 801-3. Operating temperature ranges from 0°C to 60°C. Storage temperature expands from -40°C to 85°C. Relative humidity can reach 95% without condensation. Operating altitude is up to 5000 meters.
