The ABB 1VCF750132801 is a high-performance Binary Input/Output (BIO) module specifically designed for the REF 542plus multi-function protection and control unit. This module functions as a critical interface between the protection relay and the primary switchgear, allowing for the acquisition of binary signals (such as breaker status or alarms) and the execution of control commands (such as tripping or closing signals). Operating within a voltage range of 19-72 VDC, it is engineered for reliability in demanding medium-voltage distribution environments.

Application Fields
This module is primarily used in electrical power distribution and industrial automation. It is a standard component for substation automation systems, power plants, and large-scale industrial facilities using the REF 542plus platform. It is essential for monitoring circuit breaker positions, isolator status, and external trip signals, while also providing the output contacts necessary for interlocking and protection logic execution.
Product Instructions
Installation should only be performed by qualified personnel while the main relay unit is powered down. The module is inserted into the designated slot on the rear of the REF 542plus chassis. Ensure the module is firmly seated and secured with the provided screws to maintain proper electrical contact with the backplane. When replacing an older version of the interconnected module, it is recommended to use the common ground kit (2RCA032194A0001) to consolidate the negative poles of the binary inputs into a single wire for improved signal integrity. Configuration of the inputs and outputs is managed through the ABB HU_SET or Automation Builder software tools.
FAQ: Common Questions and Answers
Q: Can this module be used with a 110V DC control circuit? A: No, the 1VCF750132801 is rated specifically for 19-72 VDC. For 110V systems, you must use a BIO module with a higher voltage rating, such as the BIO3 88-132VDC version.
Q: What is the benefit of the “14VDC” designation in the description? A: This refers to the input switching threshold. It ensures that any signal below 14V is ignored as noise, while signals above this level are reliably registered as an “ON” state.
Q: Is there a version available for maritime or harsh environments? A: Yes. You can order a DNV-certified (coated) version of this module to provide extra protection against salt mist and humidity by following the specific ABB coating order codes.
