Schneider Electric 140DDI3530 Discrete Input Module

Schneider Electric's 140DDI3530 TSX Quantum discrete input module delivers 32 sinking 24 VDC digital inputs for expanding MODICON TSX Quantum PLC systems. The 32 inputs are organized as four groups of eight on the Quantum backplane rack, with group-to-bus isolation and positive-logic operation, and channel- and module-level LEDs provide status visibility. It is designed to monitor field devices such as pushbuttons, limit switches, proximity sensors, and other 24 VDC digital inputs, and passes their status to the PLC CPU for control logic execution. Common applications include industrial automation, process control, water and wastewater plants, packaging machinery, and other environments where high-density digital input acquisition is required. Compatible with SCHNEIDER Automation / MODICON TSX Quantum platforms and PLCs, it mounts on a Quantum backplane rack and provides 24 VDC sinking inputs for reliable digital input monitoring.
