Honeywell Analytics HA20- 2 Channel Controller

HA-210 has been discontinued since December 31, 2017

The Honeywell HA20 2 channel digital gas controller is designed to work in the harshest industrial or commercial environments. A NEMA4x and explosion proof enclosure allows you to place the controllers in all hazardous locations to monitor for toxic gases, combustible gases, and oxygen deficiency.

The controllers are easy to install and feature large graphical LCD display, standard 4-20mA inputs, and non-intrusive inputs for hazardous areas.

HA20 controller is also user friendly and easy to configure. A Graphic LCD Display shows monitored data as bar graphs, 30 minute trends and engineering units. A touch-and-magnetic keypad allows for nonintrusive operation in potentially hazardous locations. Cal Mode offers pushbutton zero /span calibration for direct sensor interface applications. Authorization Mode allows locking of critical configuration variables.

Measurement ranges in engineering units, adjustable alarm set-points, optional serial interfaces, and many other features offer flexibility to meet most demanding applications. Relay outputs allow control of beacons, horns and other alarm events. Three adjustable alarm levels are provided per channel. Two standard SPDT common alarm relays are for HORN, HIGH, WARN or FAULT alarm conditions

The HA20 controller meets and exceed national, state and local safety regulations. Even the low-cost NEMA 4X model is CSA certified, CSA certified to C22.2 NO. 152 for combustible detection and Class I, Div. 2, Groups A,B,C,D CE mark NEMA 4X (Div. 2 certified).Explosion-Proof wall mount packaging options are also available.
