XVC768115 3BHB007211R115

Product Introduction

The XVC768115 3BHB007211R115 is a versatile I/O termination unit from ABB, designed as a critical interface in Advant Open Control System (OCS) architectures. It serves as the physical connection point between field devices (sensors, actuators) and the control system’s I/O modules, providing organized wiring, signal protection, and diagnostic visibility.

Engineered to handle both analog (4-20 mA, 0-10 V) and digital (24 V DC) signals across 16 channels, the XVC768115 3BHB007211R115 simplifies wiring in industrial control cabinets. Its robust design ensures reliable signal transmission in harsh environments, while 2.5 kV isolation protects sensitive control electronics from electrical noise. Whether used in power generation, chemical processing, or alongside legacy systems like the CMA136 3DDE300416 analog module, this termination unit streamlines installation, reduces wiring errors, and enhances system maintainability.

Core Advantages and Technical Highlights

Mixed Signal Support

The XVC768115 3BHB007211R115 accommodates both analog and digital signals, eliminating the need for separate termination units in mixed I/O environments. In a water treatment plant’s filtration system, it can simultaneously terminate:

4-20 mA signals from pressure transmitters

24 V DC digital inputs from flow switches

0-10 V outputs to valve positioners
This versatility reduces cabinet space requirements and simplifies spare parts inventory.

Enhanced Signal Integrity

With 2.5 kV AC isolation between field wiring and the control bus, the XVC768115 3BHB007211R115 minimizes electromagnetic interference (EMI) and ground loops. In a steel mill’s hot rolling line—where high-voltage motors generate electrical noise—this isolation ensures stable signal transmission from temperature sensors to the AC400 controller, preventing false readings that could disrupt the rolling process.

Diagnostic Visibility

Integrated LEDs provide at-a-glance status for power, channel activity, and faults. In a pharmaceutical batch system, a red fault LED immediately flags a loose wire in a critical pH sensor circuit, allowing technicians to resolve the issue before it affects product quality. This reduces troubleshooting time by up to 60% compared to non-indicated termination blocks.

Typical Application Scenarios

Advant OCS Process Control

In a natural gas processing plant using the Advant OCS, the XVC768115 3BHB007211R115 terminates signals for a distillation column control loop:

Analog inputs: 4-20 mA from temperature (RTD) and pressure transmitters

Digital inputs: 24 V DC from level switch contacts

Analog outputs: 4-20 mA to reflux pump speed controllers
Wires from field devices connect to the unit’s screw terminals, which then route signals to the CMA136 3DDE300416 analog module in the AC400 rack. Its organized layout simplifies loop checking during maintenance shutdowns.

Legacy System Retrofits

When upgrading a MasterPiece 200/1 system, the XVC768115 3BHB007211R115 provides a modern termination solution that interfaces with existing I/O modules. In a pulp and paper mill, it replaces aging terminal blocks, enabling easier integration of new sensors while maintaining compatibility with legacy controllers. The unit’s diagnostic LEDs improve visibility into system health, which was limited in the original installation.

Installation, Commissioning and Maintenance

Installation Preparation

Mount the XVC768115 3BHB007211R115 on a 35 mm DIN rail, leaving 50 mm clearance above/below for wiring access.

Connect field wiring (0.5-2.5 mm²) to terminals 1-32, following the unit’s labeling for analog/digital signal separation.

Link the termination unit to the I/O module via a 26-pin ribbon cable (supplied with the unit).

Connect 24 V DC power to the unit’s auxiliary terminals, ensuring correct polarity to avoid damage.

Verify all connections against the wiring diagram before powering on the control system.

Maintenance Suggestions

Daily Checks: Confirm green power LED is illuminated and no fault LEDs are active.

Quarterly Inspections: Tighten terminal screws to 0.6 Nm, check for corrosion, and clean dust with compressed air.

Troubleshooting: If a channel signal is lost, use a multimeter to test continuity between the terminal and field device. A faulty channel may indicate a loose connection or internal terminal block damage—replace the XVC768115 if terminal contacts are worn.
