HA71N4-8 8 Channel Controller by Honeywell Analytics

Honeywell Analytics offers a family of gas detection controllers that monitor 2, 4, 8 or 16 points of gas detection. Our controller family delivers robust safety while being cost effective.

The Honeywell digital gas controllers are 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. An optional RS-485 Modbus slave port allows up to 128 HA 40 s to be multi-dropped onto a single data highway for interrogation by another Modbus master. A 10-BaseT Ethernet cable is also available for utilizing the popular Modbus TCP/IP protocol.

The HA-20 and HA-40 controllers are designed to provide simultaneous display and alarm functions for two or four 4-20mA sensor transmitters. The 4-20mA inputs are standard equipped and ideal for interfacing to sensor transmitters that may be long distances from the controller.

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.
