Modular design and a variety of communication protocols support, so that the controller can easily adapt to a variety of industrial automation application requirements.

Safety:

Compliance with IEC 61508 standard and SIL 2 certification for safety applications ensures the controller's excellent performance in safety control.

ELFD Controller Carrier

The ELFD Controller Carrier provides a mounting platform for up to two SafetyNet Controllers (8851-LC-MT). It can also accommodate a Power Supply Monitor module (8410-NS-PS) which can monitor the health of up to two 8913-PS-AC, four 8914-PS-AC power supplies and the 12V supply to Intrinsically Safe Modules (when these are used). For each Controller there is a serial port connector and a manually operated ““Change State” button. The Carrier also provides terminals that are used when earth leakage fault detection is required.

Application Areas

Electric power plants: monitoring and controlling generators, steam turbines, governors and other equipment to ensure the stable operation of the power generation system.

Power transformer and distribution: used in substations and distribution stations to monitor and control transformers, circuit breakers, voltage regulators and other equipment.

Power grid control: applied in monitoring, scheduling and control of power systems to ensure the stability and reliability of power networks.

Industrial process control: in manufacturing and chemical plants for automating and monitoring production processes.

Energy Management System: supports the monitoring, analysis and optimisation of energy systems to improve energy efficiency.

Power Generation Scheduling: Coordinates and optimises the operation of power generation plants to meet electricity demand.

Smart Grid: in smart grids to support the digitisation and intelligence of the grid.
