Instructions
Precautions
WARNING! All wiring must be performed by a qualified
electrician or instrumentation engineer. See diagram for
terminal designations and wiring examples. Consult factory
for assistance.
WARNING! Avoid shock hazards! Turn signal input, output,
and power off before connecting or disconnecting wiring, or
removing or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un électricien
ou ingénieur en instrumentation qualifié. Voir le diagramme
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.
API maintains a constant effort to upgrade and improve its products.
Specifications are subject to change without notice. See api-usa.com for
latest product information. Consult factory for your specific requirements.
WARNING: This product can expose you to chemicals includ-
ing nickel, which are known to the State of California to cause
cancer or birth defects or other reproductive harm. For more

Electrical Connections
See wiring diagrams. Observe polarity. If the output does not
function, check wiring and 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!
Each product is factory configured to your exact input and out-
put ranges as indicated on the serial number label. The input
range is factory pre-configured (at 24°C ±1°C).
Check label for module operating voltage to make sure it
matches available power.
The power supplies are fuse protected and the unit may be
returned to API for fuse replacement.
Outputs
For milliamp output ranges, determine if your devices provide
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. See note
about terminating an unused mA output channel.

When using DC power, either polarity is acceptable, but for
consistency, wire positive (+) to terminal 25 and negative (–)

Mounting to a DIN Rail
Install module vertically on a 35 mm DIN rail in a protective
enclosure away from heat sources. Do not block air flow. Allow
1" (25 mm) above and below housing vents for air circulation.
1. Tilt front of module downward and position the lower spring
clips against the bottom edge of
DIN rail.
2. Push front of module upward until
upper mount snaps into place.
Removal
Avoid shock hazards! Turn signal
input, output, and power off.
1. Push up on bottom back of
module.
2. Tilt front of module downward
to release upper mount from top
edge of DIN rail.
3. The module can now be
removed from the DIN rail.
Calibration
Front-mounted Zero and Span potentiometers for each channel
can be used to compensate for load and lead variations.
1. Apply power to the module and allow a minimum 20 minute
warm up time.
2. Using an accurate calibration source, provide an input to
the module equal to the minimum input required for the
application.
3. Using an accurate measurement device for the output,
adjust the Zero potentiometer for the exact minimum output
desired. The Zero control should only be adjusted when the
input signal is at its minimum. This will produce the cor-
responding minimum output signal. For example: 4 mA for
a 4-20 mA output or –10 V for a ±10V output.
4. Set the input at maximum, and then adjust the Span pot for
the exact maximum output desired. The Span control should
only be adjusted when the input signal is at its maximum.
This will produce the corresponding maximum output
signal. Example: for 4-20 mA output, the Span control will
provide adjustment for the 20 mA or high end of the signal.
5. Repeat adjustments for both output channels for maximum
accuracy.
