DEIF 1044220060F Mains Measurement Module

The DEIF 1044220060F is a dedicated mains measurement module designed for use with DEIF generator controllers and power management systems. This module provides accurate monitoring of grid or mains parameters including voltage, frequency, and phase angle, enabling synchronization of generator sets with the grid and protection against grid disturbances. The module is an essential component for applications requiring generator-to-mains synchronization or grid parallel operation.

Measurement Capabilities

The 1044220060F continuously monitors three-phase mains or grid parameters with high accuracy. Measured values include phase-to-phase voltages, phase-to-neutral voltages, frequency, and phase angle relative to the generator. The module also detects voltage unbalance and phase sequence, providing essential information for safe grid connection. All measurement data is transmitted to the connected DEIF controller via the CAN bus interface, enabling the controller to perform synchronization, protection, and power management functions.

Synchronization Support

The primary function of the 1044220060F is to provide the measurement data required for generator-to-mains synchronization. The module continuously measures the mains voltage, frequency, and phase angle, transmitting this data to the DEIF generator controller. The controller uses this information to match the generator voltage and frequency to the mains and to close the synchronizing breaker at the optimal moment. This ensures smooth connection without electrical transients that could damage equipment or cause system disturbances.

Protection Functions

In addition to synchronization support, the measurement module enables grid protection functions within the connected DEIF controller. The controller can monitor for grid undervoltage, overvoltage, underfrequency, overfrequency, and voltage unbalance conditions. When abnormal grid conditions are detected, the controller can automatically disconnect the generator or prevent connection, protecting both the generator and the electrical system from damage.

Integration with DEIF Controllers

The 1044220060F is designed for seamless integration with DEIF AGC and PPU series controllers. The module connects to the controller via the CAN bus interface, requiring no additional configuration beyond setting the module address. Multiple measurement modules can be connected to a single controller for applications requiring monitoring of multiple mains sources, such as dual feed systems or islanded grids. The measurement data is automatically available to the controller for display, control, and protection functions.

Installation

The module is designed for DIN rail mounting in control cabinets. Voltage connections are made via pluggable terminal blocks, with each phase and neutral clearly labeled. The module includes built-in fusing and overvoltage protection to ensure reliable operation in industrial environments. The CAN bus connection uses standard twisted pair wiring with termination resistors as required by the network configuration. The compact size allows installation in crowded cabinets with minimal space requirements.
