Description
Priced from $29,592.00 — configured to order; call CPS for an exact build quote. The price shown is the lowest configured GM128 build in Crowcon's current price book; your exact configuration is quoted in writing before you commit.
The Crowcon GM Addressable Controllers are a range of three modular gas detection controllers with identical functionality and different channel capacities, built to order for each site. Every GM controller is configured exactly to requirements - channel count, input type (4-20mA analogue, mV or digital addressable), relay outputs, mounting and power supply are all selected for the application, and the controller can be upgraded with additional functionality at any time after installation.
Addressable communications let multiple fixed detectors share a single communications loop, drastically reducing cabling, labour and installation time versus traditional home-run wiring, and analogue and addressable inputs can be mixed in one controller. Channels can be grouped into zones, all active channels can be viewed on one screen - from 3-minute trends of a single channel to analysis of up to 16 channels at a time - and a direct-to-web-page live feed allows remote viewing and configuration. Because every build is different, GM controllers are priced from the lowest configured build in Crowcon's current book and quoted exactly for your configuration - see the pricing note at the top of this page.
Build yours: tell CPS your channel count, input types and relay needs and we will spec and quote the exact GM build for your site. Call CPS Calibrations at (865) 900-8844 or email info@cpscalibrations.com.

- Configured to order - every GM controller is built to the site specification: channel count, input types, relay outputs, mounting and power supply
- Fully modular design - the controller includes only what the application needs, reducing complexity and cost, and can be upgraded after installation
- Analogue or addressable inputs - 4-20mA/mV home-run wiring, digital addressable loops that carry multiple detectors on one cable run, or a mix of both
- Group channels into zones and display all active channels on the same screen
- Live data views from 3-minute trends of one channel to analysis of up to 16 channels at a time
- Direct-to-web-page live feed - view data and configure the controller remotely from a fixed screen or mobile device
- 19 inch rack mounted, with enclosure options available for GM16 and GM64
- Easy navigation and configuration from the front panel minimises time spent in potentially hazardous locations
