Honeywell HA71

The Honeywell HA-71 has a simultaneous display and alarm functions for up to 16 input variables, and can expand with 10 additional HA71 units to provide up to 160 points of gas detection.

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. Nonvolatile memory retains all configuration data indefinitely.

Analog inputs may be accepted and conditioned via sensor specific analog input cards. Alternatively, the standard Modbus Master port allows input data to be retrieved from Modbus slave devices including the many Modbus compatible Honeywell Analytics sensor transmitter products.

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.

A RS-485 Modbus slave port allows up to 128 HA71’s to be multidropped onto a single data highway for interrogation by another Modbus master. HA71’s may also be cascaded by connecting one unit’s master port to another’s slave port 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.

HA71 facilitates monitoring of ambient gas detection, rotating machinery, tank levels, flow, temperature and other controls.
