ABB 70BK03C-E HESG447440R0001 Bus Coupling Module
Product Overview
The ABB 70BK03C-E (Part No: HESG447440R0001) is a modular bus coupling unit engineered to seamlessly interface ABB’s PROCONTROL P distributed control system (DCS) with external RS232-based devices. Designed for rugged industrial environments, it provides reliable data exchange, high signal integrity, and plug-and-play simplicity to support critical process control applications.
This module sits in a standard PROCONTROL P I/O rack slot and draws power directly from the backplane bus, eliminating the need for separate power wiring. Its automatic initialization and configuration capabilities significantly reduce commissioning time, while its durable construction withstands harsh conditions such as vibration, temperature extremes, and electromagnetic interference.

Applications
The 70BK03C-E HESG447440R0001 is ideal for a wide spectrum of industrial scenarios:
-
Process Control Systems: Bridges meters, analyzers, and serial controllers to the central DCS for synchronized operation and data logging.
-
Legacy Equipment Integration: Enables older RS232-only field instruments—such as flow meters, temperature transmitters, and pressure modules—to communicate with modern control architectures.
-
Remote Terminal Units (RTUs): Acts as a gateway in remote automation shelters, gathering serial data from multiple devices and relaying it upstream securely.
-
Manufacturing Execution Systems (MES): Provides a reliable data feed from shop-floor serial devices into enterprise-level production management platforms.
-
Oil & Gas and Chemical Plants: Ensures continuous, error-monitored data flow in critical processes such as reactor control, batch sequencing, and safety interlocks.
Advantages
-
Hot-Swap Capability
Allows removal and insertion during live operation without disrupting the remainder of the rack or system, maximizing uptime. -
Auto-Detection and Configuration
On insertion, the module automatically identifies its slot address and network parameters, speeding up installation and reducing manual setup errors. -
Industrial-Grade Durability
Built to withstand shock, vibration, and wide temperature swings, ensuring consistent performance even in the harshest plant environments. -
Compact Footprint
At only 250 × 170 × 157.4 mm, it conserves cabinet space while offering high functionality, and its low 0.447 kg weight eases handling and mounting. -
Seamless ABB Integration
Fully compatible with PROCONTROL P I/O families and ABB’s suite of control hardware, software, and support services, providing a unified solution.
