Interface and Signal Details

The KL3003X1-LS1 connects field contacts to the carrier backplane through dedicated slot contacts. Each module handles one input channel and reports state changes to the controller. Therefore, technicians gain granular diagnostics and simple fault isolation. The unit seats in a standard carrier slot and needs no external power wiring.

Physical and Environmental Parameters

The module measures roughly 140 mm by 88 mm by 25 mm and weighs about 0.18 kg. Its slim housing allows dense channel counts inside compact carriers. Meanwhile, the 0°C to 60°C operating range covers typical control room conditions. The on-board filtering suppresses contact bounce before signals reach the logic stage.

Why This Module Matters

Plant teams value the KL3003X1-LS1 for its compact size and predictable contact sensing. The energy storage components steady input levels during switching events. As a result, nuisance trips drop and maintenance windows shorten considerably. Technicians also appreciate the clear channel marking and tool-free slot swaps.
