Emerson KC4011X1-BQ1 Simplex DO 40-Pin Terminal Block

The KC4011X1-BQ1 serves as a simplex discrete output mass terminal block within Emerson’s industrial automation ecosystem. This module provides a reliable interface between field wiring and control systems in demanding process environments. Engineers value this component for its robust 40-pin configuration and straightforward installation.

Physical Dimensions and Weight

The KC4011X1-BQ1 features a compact form factor that fits standard DIN rail mounting systems. Its dimensions measure approximately 150 mm in length, 90 mm in width, and 45 mm in depth. The unit weighs roughly 0.35 kg, which allows easy handling during field installation. These measurements ensure compatibility with existing cabinet layouts and panel designs.

Terminal Configuration and Interface Specifications

This mass terminal block offers 40 discrete output points through a simplex architecture. Each pin carries a maximum current rating of 2 A at 24 VDC. The KC4011X1-BQ1 accepts wire sizes ranging from 0.5 mm² to 2.5 mm². Moreover, the terminal block includes screw-type connections for secure wire termination. The module operates within a temperature range of -20°C to 60°C.

Energy Storage and Component Count

The KC4011X1-BQ1 contains no internal energy storage elements, as it functions purely as a passive termination interface. The assembly comprises 40 individual terminal points, two mounting brackets, and one protective cover. Additionally, the unit includes labeled identification strips for each output channel. This design simplifies maintenance and troubleshooting procedures.
