Allen-Bradley 1407-CGCM Combination Generator Control Module

Product Overview

The 1407-CGCM is a high-performance, integrated solution designed by Allen-Bradley for comprehensive generator management. This module combines excitation control, synchronization, and protective functions into a single, robust hardware platform, specifically engineered for complex power generation environments. By providing precise sensing of generator voltage, current, and frequency, it ensures stable load sharing and optimal real/reactive power distribution across multiple generator sets, making it a cornerstone for reliable industrial power systems.

Core Technical Advantages

This control module features 3-phase current sensing with cross-current compensation to maintain superior system stability during parallel operations. Its high-accuracy metering allows for exacting control of the generator field and power factor. Built to withstand demanding conditions, the hardware supports a wide operating temperature range and is optimized for 24V DC nominal power systems. The integration of load share resolution at 0.1% of full-scale voltage significantly reduces the risk of power fluctuations in critical infrastructure applications.

Technical Specifications

Installation & Engineering Guide

The module must be powered by a certified 24V DC power supply or a battery system compliant with ATEX certifications if used in hazardous zones. During installation, ensure that the Current Transformer (CT) inputs are correctly phased for 3-phase current sensing to facilitate accurate cross-current compensation. Maintain adequate spacing in the control panel to allow for convective cooling, as the unit dissipates approximately 30W during full-load operation. All field sensing connections should be verified for tight terminal seating to prevent signal interference or metering errors.

Engineering Advantages

Utilizing this Allen-Bradley module simplifies generator control by consolidating excitation and synchronization logic, which reduces the total number of components and wiring points in a control cabinet. The sophisticated real and reactive power load sharing algorithms allow for smooth transients when generators are brought online or removed from the bus. With its robust storage temperature rating of up to 85°C, the module is exceptionally resilient for use in remote power stations or mobile generator units where environmental conditions vary significantly.
