Carlo Gavazzi VMUOCAI3XXEM pulse concentrator extension module with 3 digital inputs, DIN rail mounting and local bus connection for VMU pulse concentrator systems.
£99.14
The Carlo Gavazzi VMUOCAI3XXEM is a compact pulse concentrator extension module designed for Carlo Gavazzi VMU pulse concentrator systems. It provides 3 additional digital inputs, allowing pulse signals from meters and field devices to be collected and integrated into wider energy monitoring and automation networks.
As part of the Carlo Gavazzi VMU Series, the VMUOCAI3XXEM is used alongside compatible master modules such as the VMU-MC pulse concentrator. Each extension module adds further input capacity, making it suitable for applications where multiple electricity, gas, water, heat or utility meters need to be monitored from a central system.
With DIN rail mounting, local bus connection and UL approval, the VMUOCAI3XXEM is ideal for metering panels, building management systems and industrial control cabinets requiring reliable pulse signal expansion in a compact modular format.
The VMUOCAI3XXEM expands the input capacity of Carlo Gavazzi pulse concentrator systems, allowing additional pulse-output devices to be connected to a monitoring network. This is useful where multiple utility meters or consumption counters need to be brought into a single supervisory system.
By linking to a compatible master module through the local bus, the extension module helps simplify panel wiring while maintaining a modular architecture that can be scaled to suit the installation. This makes it well suited to commercial buildings, industrial sites and energy efficiency projects where reliable pulse counting is required.
