The ABB HBS01-EPD is a horizontal mounting base designed for ABB Ability Symphony Plus SD Series I/O systems. It serves as a Module Termination Unit (MTU), providing mechanical mounting, electrical connections, and field signal termination for compatible analog and digital I/O modules.
In industrial automation, reliable signal connections are essential for accurate process monitoring and equipment control. Sensors, transmitters, switches, and actuators continuously exchange information with the distributed control system (DCS). Therefore, a dependable termination and mounting solution is necessary to connect field devices with the system's I/O modules.
The HBS01-EPD addresses this requirement through a compact horizontal mounting design. It supports externally powered field signals and provides system power for compatible analog output applications. Furthermore, its terminal arrangement allows field wiring to be connected directly or through suitable marshaling cables.
As part of ABB's Symphony Plus SD Series hardware family, this mounting base supports flexible industrial I/O configurations. It is particularly useful in applications where multiple field signals must be organized and connected within a structured control cabinet.
Unlike a conventional standalone controller, the HBS01-EPD functions as an interface and mounting component. Its role is to provide the physical and electrical connection between compatible I/O modules and the wider control system.
The HBS01-EPD is designed to accommodate up to sixteen process signals within a horizontal mounting arrangement. Its electrical connection structure supports different types of compatible analog and digital I/O modules.

One of the main advantages of the HBS01-EPD is its ability to accommodate different field signal wiring arrangements.
The base incorporates two 16-point headers. These provide connections to two compatible pluggable terminal blocks, allowing field signal wires to connect directly to the mounting base.
Alternatively, suitable SPK0x_-yy marshaling cables can be used when field wiring is terminated on third-party termination hardware.
This arrangement provides flexibility for different cabinet layouts and installation requirements.
The HBS01-EPD supports a range of ABB SD Series analog and digital I/O modules.
Its supported module family includes:
AI01 and AI02 analog input modules.
AI05 and AI06 analog input modules.
AO01, AO02, and AO05 analog output modules.
AD11 analog and digital interface module.
DI01, DI02, DI03, and DI04 digital input modules.
DO01, DO02, and DO05 digital output modules.
PI01 pulse input module.
This compatibility allows the mounting base to support different process control requirements within the same general I/O architecture.
However, the exact module and wiring configuration must be verified before installation.
The EPD configuration is designed for field devices that receive power externally. It also provides system power for compatible analog output applications.
This arrangement is useful when field devices have their own power sources or when the control system requires different electrical arrangements for input and output signals.
Consequently, the HBS01-EPD provides a practical termination solution for diverse industrial instrumentation.
The mounting base features a locking mechanism that secures it to a standard 35 mm DIN rail.
Its horizontal installation design helps organize modules in a consistent arrangement. Moreover, optional mechanical keying can prevent the insertion of an incorrect I/O module type.
These features help improve installation accuracy and reduce the possibility of configuration mistakes during maintenance.
The ABB HBS01-EPD belongs to the Symphony Plus SD Series I/O hardware ecosystem.
Symphony Plus is an ABB distributed control system platform designed for industrial process automation. Its architecture supports process monitoring, equipment control, field signal acquisition, and communication between different automation components.
Within this architecture, the HBS01-EPD provides the termination and mounting interface for a compatible I/O module.
Its position in the control architecture can be understood through three main functions:
Field Device Connection: Sensors, transmitters, switches, and other instruments generate electrical signals that represent process conditions.
I/O Module Interface: The HBS01-EPD provides the physical connection for compatible I/O modules, allowing field signals to enter or leave the control system.
System Integration: The installed I/O module communicates through the HN800 I/O bus, allowing process information to be exchanged with the wider Symphony Plus control architecture.
An important advantage of the SD Series is its hardware flexibility. ABB documentation indicates that different SD I/O module and base configurations can operate within a common HN800 I/O bus architecture, subject to the specified module and system compatibility requirements.
This provides greater flexibility when designing or maintaining industrial control installations.

Power Generation
Power plants use numerous sensors and electrical instruments to monitor generator auxiliary systems, temperature, pressure, flow, and other operating parameters.
Compatible Symphony Plus I/O modules mounted on the HBS01-EPD can support the collection and distribution of these process signals.
Oil and Gas Processing
Oil and gas facilities rely on continuous monitoring of pressure, temperature, flow, and equipment status. The HBS01-EPD provides a structured connection point for compatible I/O modules used in these applications.
Water and Wastewater Treatment
Water treatment facilities use instrumentation to monitor pumps, valves, tank levels, flow rates, and treatment conditions. The mounting base supports the installation of compatible I/O modules for these process signals.
Chemical and Petrochemical Industries
Chemical production requires coordinated monitoring of multiple process variables. Proper signal termination helps organize field wiring and supports reliable communication between instruments and the DCS.
Pulp and Paper Manufacturing
Paper manufacturing involves complex machinery and continuous production processes. Compatible ABB I/O configurations can support the monitoring and control of different equipment and production stages.
General Process Automation
Beyond these industries, the HBS01-EPD can be used in other Symphony Plus installations requiring horizontal mounting and termination of compatible analog or digital signals.
Correct installation is important for ensuring reliable electrical connections and long-term operation.
Although the HBS01-EPD is a mounting and termination component rather than an independent controller, its condition directly affects the connection between field wiring and the installed I/O module.
The following practices are recommended:
Verify Model Compatibility: Confirm that the selected I/O module is supported by the HBS01-EPD before installation.
Inspect the Mounting Base: Check the housing, locking mechanism, and connection headers for visible damage.
Check DIN-Rail Installation: Ensure that the base is securely attached to the 35 mm DIN rail.
Verify Terminal Connections: Inspect terminal blocks and wiring connections to prevent loose contacts.
Check Field Power: Confirm that external field power and system-powered analog output arrangements meet the applicable electrical requirements.
Review Wiring Diagrams: Follow the ABB installation documentation for signal assignments, polarity, grounding, and wiring arrangements.
Perform Functional Testing: After installation, verify the signal connections and confirm that the associated I/O module operates correctly.
It is also important to remember that the HBS01-EPD does not support hot swapping. Therefore, technicians should follow the appropriate shutdown and electrical isolation procedures before replacing or modifying the mounting base.
Regular inspections can help identify damaged terminals, loose connections, contamination, and other problems before they affect the wider control system.
