Interface and Wiring Details

The KL4502X1-MA1 connects to the control backplane through a dedicated connector. Field wiring lands on screw-type terminals, and each channel offers isolated dry contacts. Consequently, installers can wire loads directly without extra interface hardware. The block occupies a single chassis slot and draws power from the shared rail.

Physical and Environmental Parameters

The module measures roughly 170 mm by 105 mm by 30 mm and weighs about 0.30 kg. Its compact housing fits standard cabinets and simplifies panel layout. Meanwhile, the 0°C to 60°C operating range suits most control room environments. The relay contacts handle inductive loads well thanks to the suppression circuitry.

Why This Module Matters

Plant teams value the KL4502X1-MA1 for its robust relay switching and easy maintenance. The on-board energy storage absorbs coil transients during de-energization. As a result, contact arcing stays low and relay life extends. Technicians also appreciate the clear terminal labeling and quick access.
