Schneider 140DDI35300C Modicon Quantum 24V DC Input Module

Schneider Electric Modicon Quantum 140DDI35300C Discrete Input Module

• This module accepts 32 discrete inputs organized into 4 isolated groups, each containing 8 channels for simplified wiring and troubleshooting.
• It features a positive logic input configuration (sink), which simplifies integration with most PLC and sensor output types.
• The 140DDI35300C requires only 2 input words for addressing, conserving valuable processor memory and I/O mapping space.
• With a rapid response time of ≤ 1 ms for both On-to-Off and Off-to-ON transitions, it ensures precise event capturing.
• Visual diagnostics are clear and immediate thanks to 32 green LED indicators for status and a dedicated Active LED for bus communication.

Electrical Specifications and Input Characteristics

• Voltage Range: It operates with an input voltage range of 19.2 to 30 V DC, with a nominal rating of 24 V DC.
• Guaranteed States: The module recognizes State 1 (On) from 15 to 30 V DC and State 0 (Off) from -3 to 5 V DC for reliable switching.
• Current Thresholds: It requires a minimum current of ≥ 2 mA for a guaranteed On state and ≤ 0.5 mA for a guaranteed Off state.
• Overvoltage Protection: The input withstands up to 56 V during a 1.3 ms decaying pulse, protecting against voltage surges.
• Input Impedance: Each channel presents a 2500 Ohm impedance, ensuring appropriate loading on connected field devices.

Isolation, Protection, and Environmental Resistance

• Isolation Ratings: It provides 500 Vrms isolation between channel groups and 1780 Vrms isolation between the group and the backplane bus.
• Protective Coating: A conformal coating of Humiseal 1A33 protects the circuit board from moisture, dust, and chemical contaminants.
• Environmental Tolerance: It operates in temperatures from 0 to 60 °C and withstands storage temperatures from -40 to 85 °C.
• EMC Immunity: This module resists electromagnetic fields of 10 V/m and electrostatic discharge up to 8 kV on air.
• Certifications: It carries multiple marine and industrial approvals including ABS, BV, DNV, RMRS, and GOST.

Frequently Asked Questions (FAQ)

• Is this a sink or source input module?
  The 140DDI35300C uses a positive logic (sink) configuration, meaning it switches the DC common to the input circuit.
• What is the leakage current specification?
  The maximum leakage current is 200 mA at Us = 5.5 V and Uin = 4 V, ensuring it ignores false signals from leaky outputs.
