Product Features
ABB UNS0863A-P HIEE305082R0001 supports multiple digital input and output channels and can handle switching signals simultaneously.
ABB UNS0863A-P HIEE305082R0001 has signal isolation function to prevent the influence of external interference on the system.
ABB UNS0863A-P HIEE305082R0001 integrates RS485 interface and supports Modbus protocol, which allows data interaction with the host computer or other controllers.
ABB UNS0863A-P HIEE305082R0001 is compatible with ABB's DSCS (Distributed Control System) communication standard, realizing seamless cooperation with other modules.
ABB UNS0863A-P HIEE305082R0001 utilizes a redundant power supply design to ensure that critical signal transmission is maintained in the event of a mains power failure.
ABB UNS0863A-P HIEE305082R0001 has a built-in self-diagnostic function that monitors the module status in real time and outputs a fault alarm signal.
Product Using Principle
ABB UNS0863A-P HIEE305082R0001 collects digital signals from external devices, such as generator circuit breaker status and protective device trip commands, through an opto-coupler, converts them into logic levels and transmits them to the Unitrol F controller.
It receives control commands from the controller, such as excitation current regulation, system start/stop, and actuates external actuators, such as thyristor triggering modules, alarm indicators, through relay contacts or transistor outputs.
It works in conjunction with the other modules of the Unitrol F excitation regulator to form a complete closed loop excitation control. It communicates with the host computer or SCADA system via Modbus protocol to realize remote monitoring and parameter adjustment.
Product Application
In the synchronous generator of thermal power plant and hydropower plant, ABB UNS0863A-P is responsible for monitoring the generator terminal voltage, current and other signals, and adjusting the excitation current according to the regulator's instruction to ensure voltage stability and reactive power distribution.
ABB UNS0863A-P can be used for start/stop control and condition monitoring of diesel generators or uninterruptible power supplies.
In automobile manufacturing, chemical industry and other industries, ABB UNS0863A-P is used as an I/O extension module of PLC or DCS system to realize equipment start/stop, process parameter monitoring and fault alarm.
ABB UNS0863A-P can be connected with sensors and actuators to complete the digital acquisition of temperature, pressure and other physical quantities and the execution of control instructions.
