1 General Description

The Honeywell Analytics HA20 2-Channel Controller is designed to display, and control alarm event switching for two inputs. Inputs are typically voltage or 4-20mA current from transmitters, monitors or other analog output devices. The HA20 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 conﬁgurable 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) 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 conﬁguration is via user friendly menus and all conﬁguration data is retained in nonvolatile memory during power interruptions. The HA20 front panel shown in Figure 1-1 displays the bar graph data screen. The ﬁve button symbols below the display are magnetically activated using the magnetic wand (supplied) without opening the enclosure. Opening the enclosure door provides access to the “touch” keypad as shown in Figure 1-2.

1.1 Data Display Screens

The HA20 Controller offers three modes for displaying monitored data, as shown in Figure 1-3.

Figure 1-3. Data Display Screens

1.1.1 Main Data Screen

The HA20 Main Data screen shown in Figure 1-3 allows each channel to be viewed simultaneously. Engineering unit values and bar graph values are both displayed in real time. Arrows below the bars indicate alarm trip point values, making it easy to identify channels at or near alarm level. The direction the horizontal 45º side arrow points indicates either a HIGH or LOW trip point. In Figure 1-1 where Ch 1 points right indicating high trip levels and Ch 2 points left indicating low trip levels. Left and Right hand arrows located at the ends of each bar graph point towards Channel Alarm LED’s on the front panel associated with this reading. The 10-digit ASCII ﬁelds for identifying engineering units and Channel ID for each channel are also shown on the Main Data screen.

1.1.2 Trend Screen

1.1.3 Blind Mode Screen

The HA20 Blind Mode screen (Figure 1-3) does not allow viewing of channel engineering unit values. It only indicates the system’s alarm status and time / date. Some applications require only alarm status be displayed and prefer monitored values not be shown. A SECURITY menu (see Section 2.4) allows locking all conﬁguration parameters and having only the Blind Mode screen available for viewing.

1.3 Specications

1.3.1 Power Supply Requirements

The HA20 is equipped with an integral 15 watt (or 50 watt, depending on the conﬁguration) universal AC input / 24 VDC output switching power supply. Standard HA20 AC power requirements are 100-240 VAC 50/60 Hz @ .45 amp max (including inrush) and 20 watts steady state, applied to TB5 on the motherboard. If AC power is not available, the HA20 may also be powered with 24 VDC applied to TB1 on the motherboard. A primary DC source or back-up DC source capability should be determined by the total system power budget calculation with guard-band included. A back-up DC power source may also be connected to TB1 for automatic switchover if the AC power source fails. See Figures 3-1 & 3-2 for wiring information.

WARNING

A back-up or external DC power source DOES NOT source aux power output (TB3 - see Figure 3.1)

In addition to the Main Data screen described above, the HA20 also provides 30-minute trend screens for each channel as shown in Figure 1-3. Use the Next key to scroll between data screens.

HA20 Technical Manual

1-3

HA20 2-Channel Controller

The basic HA20 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.

• 10-0221-2, Analog Input PCB option; add wattage for each monitor connected to this board’s 24 VDC terminal

Some applications require the HA20 controller to source power for high power monitors. Both 15 watt and 50 watt power supplies, UL rated for Div 2 hazardous areas, are 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 gure 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. HA20’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.
