Description
The APD 4152 accepts a thermistor temperature input and
provides an optically isolated and linearized DC voltage or
current output.
The sensor type, temperature range and output range are field
configurable. The input type is set with switches and its range
is configured using front buttons, a multimeter and an input
simulator. This provides a versatile solution that works with all
commonly available thermistor sensors.
Microprocessor-based linearization uses 41 to 55 segments or
up to a 14th order polynomial depending on the sensor type.
The input is sampled, digitally converted to a linearized tem-
perature signal and then passed through an optocoupler to the
output stage.
Full 3-way isolation (input, output, power) make this module
useful for ground loop elimination, common mode signal rejec-
tion, and noise pickup reduction.
The low noise 18 bit analog output is isolated and can be set up
for common voltage and milliamp output types.
Output Sink/Source Versatility
Standard on the APD 4152 is a 20 VDC loop excitation supply
for the milliamp output. The output can be selectively wired for
sinking or sourcing allowing use with a powered or unpowered
milliamp device.
LoopTracker
An API exclusive feature includes a green LoopTracker LED that
varies in intensity with changes in the process input signal.
It provides a quick visual picture of your process input at all
times and can greatly aid in saving time during initial startup
and troubleshooting.
Output Test
An API exclusive feature includes an output test switch to
provide a fixed output (independent of the input) when pressed.
The output test greatly aids in saving time during initial startup
and/or troubleshooting.
The test output level is adjustable from 0 to 100% of the
output span.

Adjusting Output After Installation
It may be necessary to fine-tune the output signal after instal-
lation to account for offset, tare, lead length, or operating
temperature.
1. Press and release the Set button. This will turn on the yel-
low Status LED.
2. Use the Up and Down buttons to adjust the output to
the desired level. The Status LED will turn off during the
adjustment.
3. Once the desired output level has been met, press and
release the Set button to save the adjustment. The
“Status” LED will flash indicating that the change has been
made.
The unit has an auto Zero/Span detection for knowing which to
adjust. If the output signal is greater than 50% of the Span, the
unit will adjust the output signal Span.
If the output signal is less than 50% of the Span, the unit will
adjust the output signal Zero.
Changing I/O Setup
To reset the unit back to factory default without changing any
input switch settings press and hold the Set button while the
module is being powered up.
If using a new input switch setting, the unit will automatically
start in setup mode to allow you to calibrate and store your new
configuration.
Output Test Function
When the Test button is pressed it will drive the output with a
known good signal that can be used as a diagnostic aid during
initial start-up or troubleshooting. When pressed again, the out-
put will return to normal. The button allows hands-free operation
of the Test Mode.
The Test level can be adjusted by using the Up and Down
buttons.
The level can be set by pressing the Set button, or it can default
back to the setup value by not pressing the Set button.
Operation
The APD 4152 accepts a thermistor input and provides a linear-
ized and optically isolated DC voltage or current output.
The green LoopTracker®input LED provides a visual indication
that a signal is being sensed by the input circuitry of the mod-
ule. It also indicates the input signal strength by changing in
intensity as the process changes from minimum to maximum.
If the LED fails to illuminate, or fails to change in intensity as the
process changes, check the module power or signal input wiring.
Note that it may be difficult to see the LEDs under bright lighting
conditions.
The yellow status LED provides a visual indication of operational
modes.
Normal operation: Off
Push-to-Test mode: Steadily on
User setup mode: Blinking
Blinking Yellow LED Operational Error Codes
If an error occurs during operation, the yellow Status LED blinks
an error code. Check sensor, wiring, or consult factory.

Precautions
WARNING! All wiring must be performed by a qualified electrician
or instrumentation engineer. See diagram for terminal designa-
tions and wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or remov-
ing or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un élec-
tricien ou ingénieur en instrumentation qualifié. Voir le dia-
gramme pour désignations des bornes et des exemples de
câblage. Consulter l'usine pour assistance.
ATTENTION! Éviter les risques de choc! Fermez le signal
d'entrée, le signal de sortie et l'alimentation électrique avant
de connecter ou de déconnecter le câblage, ou de retirer ou
d'installer le module.
Electrical Connections
See wiring diagrams. Observe polarity.
*Do not make any connections to unused terminals or use
them as wiring junctions for external devices. This may cause
permanent damage to the module!
Range Selection
Select ranges before installation. Use the tables on the next
page to select the I/O ranges. The module side label lists output
ranges. Ranges can also be found at api-usa.com/4152
Check the model/serial number label for module power,
options, or custom range information. A custom range uses
switch settings described in the Custom Range Table.
Models with Rreverse acting output use the same switch
settings, except the output range is reversed (4-20 mA is
20-4 mA).
1. Set switches A, B, and C from the table to set input type and
range.
2. Set switches D and E from the table to set the output range
and set switch E: V for voltage or I for current output.
For output ranges that fall between the listed ranges use the
next highest setting. The output can be trimmed using the
zero and span buttons.
Electrical Connections
See wiring diagrams at right. A multimeter and a resistance
simulator are required for setup. Observe polarity. If the output
does not function, check wiring and polarity.
The power supplies are fuse protected and the unit may be
returned to API for fuse replacement.
Input
The thermistor sensor input is connected as shown in the wir-
ing diagrams at right. If a custom input was specified, see the
model/serial number label for sensor type, temperature range
and options.
Output
For milliamp ranges, determine if your device provides power
to the current loop or if the loop must be powered by the APD
module. Typical voltage may be 9-24 VDC at your device's
terminals if it provides power to the loop.
Module Power
Check model/serial number label for module operating voltage
to make sure it matches available power.
When using DC power, either polarity is acceptable, but for
consistency with similar API products, positive (+) can be wired
to terminal 13 and negative (–) can be wired to terminal 16.
Range Calibration
Input and output ranges, if specified on your order, are factory
pre-configured (at 24°C ±1°C).
Note: Perform the following calibration procedure any time
input or output settings are changed.
1. Connect a multimeter to the output terminals 2 - 3, or 3 - 4
depending on output type. See wiring diagram at right.
2. Connect a resistance simulator to the input of the module.
3. Connect power to the unit (terminals 13, 14, and 16) and
apply power to the module.
4. Wait until the yellow Status LED starts blinking once per
second.
Low End Input Calibration
5. Use the simulator to apply the low end of the input signal.
6. Push the Set button to store the low end input value.
7. The Status LED will turn on to indicate the reading was
saved.
8. Use the Up and Down buttons to adjust the output to the
desired low output reading. For example: 4 mA for a 4-20
mA output or –10 V for a ±10V output.
9. Press and release the Set button to store the low output.
High End Input Calibration
10. Wait until the Status LED blinks once per second.
11. Use the simulator to apply the high end of the input signal.
12. Push the Set button to store the high end input value.
13. The Status LED will turn on to indicate the reading was
saved.
14. Use the Up and Down buttons to adjust the output to the
desired high output reading (i.e. 20 mA for a 4-20 mA output).
15. Press and release the Set button to store the high output.
Blinking Yellow LED Setup Error Codes
If an error occurred or invalid selection was made, the yellow
Status LED blinks an error code. Check switches A, B, C, and
input wiring.
2 1 Invalid sensor selected
2 4 Invalid thermistor selected
2 7 Invalid input setting
(Zero greater than Span)
Output Test Level Adjustment
16. Wait until the Status LED turns on and stays on.
17. Using the Up and Down buttons adjust the test output for
the desired level (i.e. 12 mA for a 4-20 mA output).
18. Press and release the Set button to store the test output.
19. Wait until the Status LED starts blinks once per second.
20. To change any value, turn off the power and repeat steps 1 to
19.
Saving Setup
21. Press and release the Set button to store the settings and
lock them into memory. The Status LED will be on during this
process.
