Products Information
The Honeywell Analytics HA-71 16 Channel Gas Detection Controller is designed to provide simultaneous display and alarm functions for up to 16 input variables.
The HA-71 delivers added value through its multiple capabilities—with simultaneous display
and alarm functions for up to 16 input variables. A graphic LCD displays monitored data as
trends, bar graphs and engineering units. Three adjustable alarm levels are provided per channel.
Relay outputs allow control of beacons, horns and other alarm events. A horn relay may be set
for steady or pulsing operation.
The HA71 is easy to configure and user friendly. Measurement ranges in engineering units, adjustable alarm set-points, dual serial interfaces and many other features combine to allow the HA71 satisfy the needs of many demanding applications. It is widely used for centralizing the display and alarm processing functions in critical multipoint monitoring applications. The optional HA-71-HMI (Human Machine Interface) software provides complete data display and storage, with real-time channel data available in 24-hour or 15-minute trends, including historical alarm and maintenance data.
HA-71 options such as discrete alarm relays per channel, 4-20mA I/O, direct sensor input conditioning and others are added by connecting appropriate 8 channel boards (2 required for more than 8 channels) to the economical I2C expansion bus. Familiar “telephone style” cables and connectors interface to this bus. This method allows versatile system configuration of options satisfying the most unusual user applications.
The HA-71-HMI (Human Machine Interface) software (optional) has the ability to monitor
up to ten HA-71 controllers simultaneously, displaying up to 160 points of detection. It
provides complete data display and storage, with real-time channel data available in 24-hour
or 15-minute trends, including historical alarm and maintenance data.
