Overview
Functional Description
The ABC11D provides communication between CENTUM systems operating on different bus networks. It allows CENTUM VP Human Interface Stations connected to Vnet to communicate with stations in other system domains, including CENTUM CS3000, CENTUM CS1000, CENTUM-XL, and micro-XL systems.
The converter supports connections across the following network types:
- Vnet for CENTUM VP, CENTUM CS3000, and CENTUM CS systems
- VLnet for CENTUM CS1000 stations
- HF bus for CENTUM-XL stations
- RL bus for micro-XL stations
Hardware Specifications
The unit provides a processor status contact output for external monitoring. This contact remains open when the CPU detects an abnormal condition. Its contact rating defines the maximum switching voltage and current for the status circuit.

Power Supply and Status Monitoring
The ABC11D-A2123 operates with a 220-240 V AC supply at 50/60 Hz. Its specified power consumption is 320 VA. Meanwhile, the ABC11D product family also offers 100-120 V AC and 24 V DC power configurations. However, these options do not apply to the specified A2123 configuration.
The processor status contact provides a separate fault-monitoring signal. When the CPU detects an abnormal condition, the contact opens. The external monitoring circuit must therefore operate within the specified maximum contact voltage and current.
System Connection Requirements
When connecting to a CENTUM CS system, the configuration requires two additional software packages:
- LHS4450 Multiple Project Connection Package
- LHS5450 Multiple Project Connection Builder
These packages support the specified multiple-project connection arrangement. Check the required software configuration when planning a connection to an existing CENTUM CS system.
Regulatory Compliance
The product family documentation lists the following regulatory markings according to power supply configuration:
- CSA safety standard for 100-120 V AC configurations.
- CE marking for 220-240 V AC configurations.
- C-Tick marking for 220-240 V AC configurations.
- KC marking for 220-240 V AC configurations.
For this model, verify the applicable markings against the unit’s nameplate and actual power supply configuration.
Frequently Asked Questions
Q: What is the main function of the Yokogawa ABC11D-A2123?
A: It connects CENTUM VP Human Interface Stations on Vnet with control stations in other Yokogawa system domains. It supports communication between different bus network environments.
