Schneider 140EDK21100 | PLC Module

The Schneider 140EDK21100 provides reliable digital signal acquisition for the Modicon Quantum platform. This PLC module features 32 discrete input channels for connecting field sensors and switches. It accepts 24 V DC sinking (NPN) inputs from limit switches and proximity sensors. Weighing only 0.36 kg, the Schneider 140EDK21100 fits into any standard Quantum rack slot. Its dimensions measure 150 mm x 100 mm x 55 mm.

Input Specifications and Channel Features

The Schneider 140EDK21100 accepts 24 V DC positive logic signals from field devices. Each input channel draws 7 mA at nominal voltage for reliable signal detection. The module groups inputs into four groups of eight channels for simplified wiring. Moreover, the Schneider 140EDK21100 includes LED indicators for each channel to show active status. Consequently, you can troubleshoot field wiring quickly without a programming terminal.

Energy Storage and Internal Components

The Schneider 140EDK21100 contains no internal battery for complete maintenance-free operation. It stores configuration data in non-volatile memory instead of battery backup. This module draws 350 mA from the 5 V DC rack power supply. Additionally, it consumes 120 mA from the external 24 V DC field power supply. The Schneider 140EDK21100 includes 32 optocouplers for electrical isolation between rack and field. Therefore, it protects your backplane from electrical noise and voltage spikes.

Connector and Installation Details

The Schneider 140EDK21100 uses a removable screw terminal block for all field wiring. This terminal block accepts wire sizes from AWG 22 to AWG 14 for flexible cabling. The module requires an external 24 V DC power supply for input circuit operation. Connect the 24 V DC positive to the COM terminal and the negative to the 0V terminal. The Schneider 140EDK21100 suits limit switches, push buttons, proximity sensors, and photo-electric sensors. It works perfectly for conveyor monitoring, position sensing, and machine guarding applications. Thus, this discrete input module delivers reliable signal acquisition for demanding industrial environments.
