Honeywell HA72

The Honeywell HA72 controller is a flexible, scalable 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.
Flexible & Feature Rich

• Configure HA72 to accept inputs from many sensor types and signal ranges. Daisy chain up to 128 HA72 controllers to expand the system to meet your needs

• Custom software auto-recognizes and addresses Honeywell gas monitors (XNX and Sensepoint XCD)

• Connect sensors directly to HA72 with bridge sensor input board, saving installation time and eliminating need for extra devices

• Use HA72 as a discrete life safety system or network to a PLC or DCS for addressable operation

• Multiple password levels allow Ethernet access according to user need or qualification

• Various enclosure options available for hazardous and non-classified areas

• Programmable relays allow for a single relay contact point of multiple devices

Advanced, User-Friendly Interface

• Full array of visual indicators (bar graphs, multicolor cells, flashing icons) and integrated alarm levels simplify and enhance monitoring, troubleshooting and trending functions

• Improved zone logic reduces false alarm incidents

• Touch & magnetic keypad allows non-intrusive operation in hazardous locations

• SD card logs over one year of data including concentration levels, alarm events, min/max, calibrations and alarm resets

• NEMA 4X, NEMA 4X Stainless Steel, full and half “19” Rackmount and NEMA 7 (Explosion-Proof) wall-mount options

• Modbus master/slave functionality allows for simultaneous sending and receiving of data, through four RS-485 serial ports

• Calibration and Authorization Modes facilitate and speed commissioning time: Mimic Mode allows viewing of other HA72 controllers on the host display
