Allen Bradley 1407-CGCM Generator Control Module ControlNet

The Allen‑Bradley 1407-CGCM is a microprocessor-based combination generator control module (CGCM) designed for generator excitation regulation, synchronization, electrical protection and power metering. It integrates seamlessly with ControlLogix and other Logix family controllers via redundant ControlNet communication, forming a complete generator management system for stationary and standby power assets. This unit supports four excitation control modes: automatic voltage regulation (AVR), field current regulation (FCR), power factor (PF) control and VAR reactive power control, with adjustable soft-start voltage ramp and over/under excitation limiting functions.

It accepts 208V line-line metering voltage and works across 20–90Hz frequency range, suitable for both brushless permanent magnet excited and brushless self-excited generators. Built-in protective functions include overvoltage, undervoltage, overfrequency, underfrequency, volts-per-hertz supervision, reverse power and loss of excitation protection. The module supports redundant CGCM pairing for hot standby generator control, with an RS232 local port for parameter setup, firmware update and diagnostic access. Front panel LEDs indicate power, network status, excitation activity, alarm and trip conditions, helping power technicians quickly identify generator faults and abnormal operating states.

This module carries hazardous area certifications including Class I Div 2 and ATEX / IECEx Zone 2 Ex ic nA IIC T4 Gc, allowing cabinet installation in classified industrial locations. It is built for continuous 24/7 operation in power control rooms, with robust resistance to voltage transients, electrical noise and temperature variation. It is widely deployed for backup generators, prime power gensets, co-generation systems and distributed power plants across oil & gas, mining, water treatment, hospitals and data center standby power systems.

Rockwell Automation officially discontinued the 1407-CGCM effective December 31, 2023, requiring engineering-level replacement migration. It is now sourced primarily as new original surplus spare for legacy generator control panels, where full system migration is not immediately practical. Power engineers, electrical maintenance teams and system integrators purchase this module for emergency replacement, panel retrofit and spare stock preservation.

We supply new original Allen‑Bradley 1407-CGCM in stock. Every unit is inspected before shipment to verify label integrity, communication port continuity and LED functionality. Standard warranty is available, and we support worldwide express delivery via DHL, FedEx or UPS. If you need to confirm compatibility with your ControlLogix firmware, generator exciter type and redundant control scheme, send your system details for technical cross-check.
