Whelen Expansion Modules

Whelen Expansion Modules

Scale your fleet's capabilities without completely rewiring the chassis using Whelen CenCom Core Expansion Modules. Modern command vehicles, heavy rescue apparatus, and tactical units require massive amounts of I/O control for lighting, gun locks, K9 deployments, and automated systems. Rather than running hundreds of wires back to a single central controller, Whelen's WeCanX Expansion Modules allow you to decentralize the network. Mount an expansion module (such as the CEM8 or CEM16) in the trunk or utility box, connect it to the Core via a single high-speed WeCanX cable, and instantly gain up to 24 additional programmable outputs precisely where you need them.

Key Features & Upfitter Specs

• Decentralized WeCanX Architecture: Drastically reduces installation time and wire weight by allowing upfitters to mount control modules locally (e.g., in the trunk) and network them via a single WeCanX cable.
• Massive Scalability: The CenCom Core system can support up to 99 total WeCanX devices, allowing fleets to effortlessly add Traffic Advisor modules, high-current modules, or 16-output modules as needed.
• Fully Programmable: Once connected to the network, every input and output on the expansion module is fully programmable via Whelen Command software for advanced automation.
• Severe-Duty Encapsulation: Engineered for the harshest environments, most Whelen expansion modules are fully potted and IP67-rated to withstand extreme moisture, salt, and intense vibration.
• High-Current Capability: Specific models (like the CEM4HC) are designed to handle massive amperage loads, allowing upfitters to safely control high-draw equipment directly from the Whelen network.
