HA40 4-Channel Controller
Revision 1 (08/08)
HA40 Technical Manual 1-2
1 General Description
The Honeywell Analytics HA40 Quad Channel Controller is designed
to display, and control alarm event switching for four inputs. Inputs
are typically voltage or 4-20mA current from transmitters, monitors or
other analog output devices. The HA40 is equipped with a Fault and
three alarm levels per channel with features such as ON / OFF delays,
latching relays and alarm Acknowledge. A dedicated horn driver circuit
for a local audible annunciator is also standard. Two standard 5-amp
alarm relays are congurable via the “alarm voting” menu to make
relays trip based on various alarm combinations. A real-Time Clock
and Calendar are also standard. Options such as 4-20mA outputs,
discrete relays for each alarm and audible annunciators are easily
added. RS-485 (Modbus RTU) or Ethernet (Modbus TCP) ports
are also available for sending data to PC’s, PLC’s, DCS’s, or other
Honeywell Analytics controllers.
A 128 x 64 pixel graphic LCD readout displays monitored data as bar
graphs, 30-minute trends and engineering units. System conguration
is via user friendly menus and all conguration data is retained in non-
volatile memory during power interruptions. The HA40 front panel is
shown in Figure 1-1 displaying the bar graph data screen. The ve
keypad symbols below the display are magnetically activated using
the supplied magnetic wand without opening the enclosure. Opening
the enclosure door provides access to the keypad buttons as shown
in Figure 1-2.
