Installation and Setup
Precautions
WARNING! All wiring must be performed by a qualified electri-
cian or instrumentation engineer. See diagram for terminal
designations and wiring examples. Consult factory for assis-
tance.
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 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.
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 lead and nickel, which are known to the State of California
to cause cancer or birth defects or other reproductive harm.

Socket and Mounting
Install module in a protective panel or enclosure. Allow space
around module for air flow. Use API 011 or API 011 FS socket.
See specifications for maximum allowable socket voltages. The
socket clips to a standard 35 mm DIN rail or can be mounted to
a flat surface.
Ranges
See the model/serial number label for module information,
module power requirements, options, and I/O range informa-
tion.
API 4400 G through API 4408 G input and output ranges are
factory configured as indicated on the serial number label.
Signal Inputs
Polarity must be observed when connecting the signal input.
Terminals 4, 5, 6, 7, 8 provide the appropriate connections for
the input signal. Polarity must be observed when connecting
the signal input.
The negative (–) connection for all inputs is connected to
terminal 5.
The positive (+) connection for input A is to terminal 4.
The positive (+) connection for input B is to terminal 6.
The positive (+) connection for input C is to terminal 7.
The positive (+) connection for input D is to terminal 8.
Signal Output
Polarity must be observed for output wiring connections. If the
output does not function, check wiring and polarity.
When a current output is ordered, it provides power to the
output current loop (sourcing).
Terminals 9 (+) and 10 (–) provide the connections for the
output. Note that the output provides power to the output loop.
Module Power
Check model/serial number label for module operating voltage
to make sure it matches available power.
AC power is connected to terminals 1 and 3.
For DC powered modules (D option), polarity MUST be observed.
Positive (+) is wired to terminal 1
Negative (–) is wired to terminal 3.
