HA40 4-Channel Controller

The basic HA40 consumes only 1.5 watts of 10-30 VDC from the integral power supply.

Optional features, and external devices such as remote transmitters, increase power consumption as described below:

•Discrete Relay PCB option; add 1.5 watt.

•4-20mA Output PCB option; add .5 watt.

•TB3 terminals 1 & 2 on the motherboard provide a maximum of 350mA output power for powering of auxiliary external devices such as relays, lamps or transmitters (see Figure 3-1). Power consumed from these terminals must be included when calculating system power consumption.10-0221-4, Analog Input PCB option; add wattage for each monitor connected to this board’s 24 VDC terminals.

Some applications require HA 40 controllers to source power for high power monitors. If the integral 15 watt power in not enough, a 24VDC, 50 watt power supply, UL rated for Div 2 hazardous areas is available. This option is also available with a Div 1 enclosure if an explosion- proof enclosure is required. (See Section 5 - Specifications.)

Warning

A backup, or external DC power source DOES NOT source auxiliary power output (see figure 3.1 TB3).

1.3.2 Relays

Two mechanical (dry contact) Common Form C relays are standard and may be mapped to various alarm events as described in Section 2.3.1. HA40’s may also be equipped with optional solid-state common Form A relays (see Section 5 - Specifications for details) in applications requiring non-arcing switching. Solid-state relays are recommended for switching of highly inductive loads.

A six mechanical (dry contact) Discrete Relay option board (see Section 3.1.6) provides dedicated Form C relays for ALARM 1, ALARM 2 and FAULT for all channels.

Warning

All mechanical (dry contact) relays are rated at 5 Amp for 28 VDC and 250 ~VAC RESISTIVE loads. IMPORTANT: Appropriate diode (DC loads) or MOV (AC loads) snubber devices must be installed with inductive loads to prevent RFI noise spikes.

Optional solid state relays are rated at 2 Amp 12-280~VAC (600Vpk). Relay wiring should be kept separate from low level signal wiring.

-25 to 50 degrees C

1.3.4 Humidity Range

0 to 90% R. H. Non-Condensing.

1.3.5 Altitude

Recommended up to 2000 meters

HA40 specifications

The Honeywell HA40 is an advanced air quality monitor that offers a multitude of features designed to provide users with accurate and real-time data regarding their indoor air conditions. As part of Honeywell’s commitment to improving the environments where people live and work, the HA40 stands out as an essential tool for continuous air quality assessment.

One of the main features of the Honeywell HA40 is its capability to measure a variety of air pollutants. It provides real-time readings of particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon dioxide (CO2), and formaldehyde levels. This comprehensive monitoring allows users to understand their air quality better and take appropriate actions to improve it.

The HA40 is equipped with advanced sensor technology that enhances its accuracy and reliability. The device utilizes laser scattering methods to precisely detect particulate matter, which offers detailed information on the concentration of airborne particles. Additionally, its integrated VOC sensor leverages photoionization to deliver quick and exact results concerning the presence of harmful compounds in the air.

Another notable characteristic of the Honeywell HA40 is its user-friendly design. The device features a clear, intuitive display that presents data in an easily understandable format. Users can quickly assess air quality levels at a glance and receive alerts when pollutants exceed predefined thresholds. Furthermore, the HA40 is compact and portable, making it suitable for both home and office use.

Connectivity is another strong point of the Honeywell HA40. The device can be connected to a smartphone application, enabling users to monitor air quality remotely. This app provides additional functionalities such as trend analysis, historical data tracking, and personalized recommendations for improving indoor air quality.

Power efficiency is also a priority with the HA40, featuring a low-power design that extends battery life and reduces the frequency of recharging. This makes it convenient for users who wish to place the monitor in various locations without the hassle of constant maintenance.

In summary, the Honeywell HA40 represents a significant advancement in indoor air quality monitoring. With its accurate sensors, user-friendly interface, and connectivity options, it empowers users to maintain a healthier living and working environment.
