Description
The universal SPA Site-Programmable Alarms
provide on/off control, warn of trouble, or provide
emergency shutdown. They accept a direct input
from transmitters, temperature sensors, and a wide
array of other monitoring and control instruments:
Current and Voltage Signals
(4-20mA, 1-5V, 0-250Vac, 0-5Aac, etc.)
23 RTD Types
(2-, 3-, and 4-wire; Pt, Cu and Ni;
10 to 1000 ohms)
8 Thermocouple Types
(J, K, E, T, R, S, B, and N)
Resistance and Potentiometer Devices
(0 to 4000 ohms)
Direct Millivolt Sources
(-10 to 120mV)
They provide two or four alarm relay outputs when a
monitored process variable falls outside of user-set
high and/or low limits. Connect the 4-wire
(line-powered) SPA to a warning light, annunciator,
bell, or shutdown system, and your process is
protected by a simple, highly reliable, independent
warning and/or shutdown strategy.
Features
Universal plant standard. Theres no need to
stock dozens of different fixed range alarm trips.
Site-programmable with on-board controls.
Your fingers are the only tools you need to get our
SPA up and running fast. All operating parameters
configure using on-board controls.
Real-time process readout. A front panel
indicator provides menu prompts during
configuration, and displays the process variable in
user-selectable engineering units.
Alarm trip and transmitter combination. The
analog output option reduces costs and installation
time when both transmitter and alarm functions are
needed at the same location (see Page 3).

On-Site Programming
Input type, range, trip points, and other frequently
changed operating parameters configure quickly and
easily from the front panel keypad. Simple prompts
on the SPAs LCD guide you through a plain-English
selection menu. Available programmable functions
include*: Input type and range Zero and full scale Alarm trip points, high or low alarm, deadband,
time delay, latching or non-latching Engineering unit readout (V, mA, %, °C, °F,
psig, mV, ohms, or optional custom engineering
units) Position of LCD decimal point for custom
engineering unit representation Upscale or downscale drive on sensor failure T/C reference junction compensation (on/off) Standard and custom linearization curves Differential or averaging of RTD inputs Current source or sink, or voltage output Security password protection

Quick Ranging Calibration
The SPA features our revolutionary Quick Ranging
Calibration method. Using the push buttons (instead
of potentiometers which can drift) and the integral
display, precise zero and span settings can be made
in seconds. All you have to do is scroll to the zero or
span value you want and a push of a button locks the
value into the SPAs memory.
* Some of the programmable functions listed are not applicable to, or
available on, all models.

Figure 3. When equipped with the Analog Output (-AO) option,
the SPA is a combination alarm trip and transmitter.
Combination Alarm and
Isolated Transmitter
When ordered with the -AO (or -AOZ) Analog Output
option, the SPA provides an analog retransmission of
the input signal that can be sent to remote monitoring/
control devices like a DCS, PLC, PC, indicator, or data
recorder (Figure 3). From the front-panel keypad, you
can adjust zero and span, and whether you want the
output to be linear or non-linear with the input.
1000Vrms isolation between the case, input, output(s),
and power supply stops the effects of harmful ground
loop noise.
Continuous Self-Diagnostics
Incorporating advanced self-diagnostics, the SPA
checks its own operation and configuration upon
start up, and then continuously monitors its status
during operation. If it senses that it is not operating
properly, it displays a message on its LCD indicating
what condition has occurred.
Custom 22-Point Linearization Curves
Current and voltage SPA models can be pro-
grammed with up to 22 custom linearization points
from the front panel keypad (Figure 4). The ability to
plot a custom linearization curve is beneficial when
non-linear input signals must be converted to linear
output representations. Typical applications include
monitoring a non-linear transducer, the level of odd-
shaped tanks, and flow meter linearization.
Security Password Protection
A security password system can be used to protect
setup data from unauthorized or inadvertant
changes. Once the password protection feature is
activated, the SPAs operating parameters cannot be
altered unless the correct password has been
entered on the keypad.
Worldwide Power Auto-Sensing
Without adjustment, the SPA accepts every AC and
DC power input (22-300Vdc and 90-260Vac). Just
apply power and youre up and running.
NOTE: Units with CE approval must be ordered with
fixed power supplies (24DC, 117AC or
230AC). See the Ordering Information tables for
details.

mA and Vdc Input Model
This SPA connects in series on a process loop, and
accepts a direct process signal from a transmitter,
transducer, or other similar instrument. It provides
two or four relay outputs if user-selectable high and/
or low limits are exceeded.
Analog Output Option
With the -AO option the SPA provides an isolated
and scaleable analog output. The analog signal is
proportional to the monitored process variable, and
is ideal for sending to a DCS, PLC, indicator,
recorder, or similar readout device.
Custom Display Parameters
The decimal position, and zero and full scale display
settings, can be selected from the keypad. This
