Honeywell HA72 Digital Gas Controllers

HA72 Gas Controller

Honeywell Analytics HA72 Digital Gas Controllers.

The HA72 controller is a flexible, scaleable gas controller that works the way you need it to. Input/Output modules allow for sets of 16, 32, 48 or 64 channel monitoring. Deploy the HA72 as a robust standalone life safety solution or addressable network with gas monitors and other field devices. User-friendly and visually powerful, the HA72 interface puts you in control of mission-critical information and allows you to share it across the enterprise via a secure, password-protected interface.

Centralize display and alarm functions with a flexible 16-64 channel controller that adapts and expands to your requirements, as a standalone solution or networkable device.
