Product Description
Overview
The KC4011X1-BP1 by Emerson is a high-reliability Carrier-Mounted Power Terminal Block for the DeltaV™ S-series Distributed Control System (DCS). It serves as a secure interface for distributing DC power from the system supply to the I/O modules, ensuring stable operation in critical process environments. This module is engineered for high availability and compliance with hazardous area regulations.
Key Features
Compact and High-Density Design
-
Designed for the DeltaV S-series carrier footprint to maximize cabinet space efficiency.
-
Supports hot-swappable installation when no I/O card is connected, minimizing process interruptions.
Electrical Performance
-
Provides low-impedance paths to maintain stable 24 VDC power to all connected I/O modules.
-
High-quality industrial insulation and corrosion-resistant terminals prevent arcing and maintain contact integrity under harsh conditions.
Environmental Durability
-
Rated for operation from -40°C to +70°C and vibration/shock resistant (10 g, 11 ms half-sine; 1 mm peak-to-peak from 2–13.2 Hz, 0.7 g from 13.2–150 Hz).
-
Compliant with ISA-S71.04 Class G3 for airborne contaminant resistance, suitable for industrial process facilities.
Hazardous Area Certification
-
Certified for ATEX Zone 2, IECEx, and Class I Div 2 installations, enabling safe use in explosive atmospheres.
-
FM and UKEX approvals ensure global compliance for hazardous location deployment.
Maintenance and Installation
-
Rotary keying system guarantees correct terminal block compatibility with installed I/O cards.
-
No user-serviceable parts; calibration is not required.
-
Removal and insertion of the terminal block are permitted only when no I/O cards are installed and no field wiring is connected.
