Wiring diagrams for Teltonika

The FMC130 also has inputs and outputs that can be used for customer-specific installations.
These connections are not always used. They depend on what needs to be measured, detected or switched.

Common examples are:

• Reading a digital signal

• Reading an analog signal

• Counting operating hours

• Detecting ignition or machine activity

• Connecting a 1-Wire device

• Switching a relay remotely

Common FMC130 connections

• DIN1 → Pin 5

• DIN2-N / AIN1 → Pin 4

• DIN3 / AIN2 → Pin 3

• DOUT1 → Pin 8

• DOUT2 → Pin 9

• DOUT3 → Pin 2

• 1-Wire Power → Pin 10

• 1-Wire Data → Pin 11

Attention!

Do not assume that every input or output is active in the platform.

Inputs and outputs must be configured before they can be used.

The FMC230 also has inputs and outputs that can be used for customer-specific installations.

Common examples are:

• Detecting whether a machine is active

• Counting operating hours

• Reading relay contacts

• Reading fault contacts

• Connecting a 1-Wire device

• Switching a relay remotely

Common FMC230 connections

• DIN1 → Pin 5

• DIN2-N / AIN1 → Pin 4

• DIN3 / AIN2 → Pin 3

• DOUT1 → Pin 8

• DOUT2 → Pin 9

• DOUT3 → Pin 2

• 1-Wire Power → Pin 10

• 1-Wire Data → Pin 11

Attention!

These inputs and outputs are customer-specific.

Only connect them when the required function and platform configuration are known.

A 1-Wire keypad can be connected to the FMC230 when the installation requires identification, access control or an immobiliser setup.

1-Wire keypad wiring instructions

• Red wire → Positive power supply

• Black wire → Ground

• Green wire → 1-Wire Data

• Yellow wire → LED / Buzzer

The 1-Wire keypad can be used to identify a user or to control whether a machine or vehicle may be started, depending on the customer setup.

The FMC230 can be used in an immobiliser setup. In this setup, a relay is used to interrupt the start signal.
This setup uses a normally closed relay contact. This means that the start signal works normally when the relay is not active. When the immobiliser is activated, the relay interrupts the start signal.

Attention!

Use relay contact 87a for this setup.

Contact 87a is the normally closed contact. It is connected to contact 30 when the relay is not active. When the relay is activated, this connection is interrupted.

Do not use contact 87 for this setup. Contact 87 is normally open and only connects when the relay is activated.

Relay contact explanation

A standard automotive relay usually has the following contacts:

• 30 → Common contact

• 87 → Normally open contact

• 87a → Normally closed contact

• 85 and 86 → Relay coil

For this immobiliser setup, the start circuit is connected through contact 30 and contact 87a.
When the immobiliser is not active, contact 30 is connected to contact 87a and the machine or vehicle can be started.
When the immobiliser is active, the relay switches and the connection between contact 30 and contact 87a is interrupted. This interrupts the start signal.

Immobiliser wiring instructions

• Relay terminal 86 → Positive control signal

• Relay terminal 85 → Digital output

• Relay terminal 30 → Starter circuit

• Relay terminal 87a → Starter circuit

• Relay terminal 87 → Not used in this setup

Attention!

Immobiliser wiring can affect machine or vehicle operation.

This setup should only be installed by a qualified person and only when the exact wiring is known.

Digital inputs

Digital inputs can be used to detect whether a signal is present or absent.
A digital input is read as:

• High, when voltage is present

• Low, when voltage is not present

This makes it possible to read signals such as:

• Relay contacts

• Fault contacts

• Machine status signals

• Mains power detection

• Ignition or contact signals

Common FMC650 digital input connections

• DIN1 → Pin 15

• DIN2 → Pin 5

• DIN3 → Pin 14

• DIN4 → Pin 4

The exact input depends on the customer setup and the configuration in the platform.

Attention!

Digital inputs should only be connected when the signal voltage is within the supported range.

Incorrect wiring can result in corrupt data or even damage to the installation.

Analog inputs

Analog inputs can be used when the tracker needs to read a variable voltage signal instead of only an on/off signal.
Examples include:

• Level sensors

• Pressure sensors

• Other voltage-based measurement signals

Common FMC650 analog input connections

• AIN1 → Pin 17

• AIN2 → Pin 7

• AIN3 → Pin 10

• AIN4 / DOUT4 → Pin 18

Attention!

Analog inputs should only be connected when the expected voltage range and platform configuration are known.

Incorrect wiring can result in incorrect measurements or damage to the installation.

Digital outputs

The FMC650 has digital outputs that can be used to switch relays remotely.
The configured outputs can include:

• DOUT1

• DOUT2

• DOUT3

• DOUT4 / AIN4

Common FMC650 digital output connections

• DOUT1 → Pin 19

• DOUT2 → Pin 9

• DOUT3 → Pin 8

• DOUT4 / AIN4 → Pin 18

DIN1 can be used to count operating hours or to detect whether the machine is active.

DIN1 wiring instructions

• DIN1 → Pin 15

When the voltage on DIN1 is high, using the same supply voltage as on the positive power supply, the machine is considered active. In that case, operating hours can be counted in the platform.
This can be used, for example, when DIN1 receives voltage from the contact, ignition signal or another signal that indicates that the machine is running.
For diesel engines, an alternative can be to use the alternator voltage when this gives a more reliable indication of machine activity.

Attention!

Always check whether the chosen signal really represents machine activity.

Do not use a signal that is only active in accessory mode if operating hours should only be counted when the machine is actually running.

The FMC650 can also be connected to CAN lines when CAN data needs to be read from a machine or vehicle.

Common FMC650 CAN connections

• CAN1L → Pin 2

• CAN1H → Pin 12

• CAN2L → Pin 6

• CAN2H → Pin 16

CAN wiring is customer-specific and depends on the machine, vehicle and available CAN signals.

Attention!

CAN connections should only be made when the correct CAN line and wiring method are known.

Incorrect CAN wiring can interfere with machine or vehicle communication.

The FMC650 supports 1-Wire connections.

1-Wire wiring instructions

• 1-Wire Power → Pin 3

• 1-Wire Data → Pin 13

• Ground → Pin 1

1-Wire can be used for supported 1-Wire devices, depending on the installation and platform configuration.

A digital output can be used to switch a relay remotely.

Relay wiring instructions

• Relay coil A1 → Positive power supply

• Relay coil A2 → Digital output

When the digital output is switched, it is connected to ground. This creates a voltage difference over the relay coil. For example, with a 24 V DC supply, the relay coil receives 24 V DC and the relay switches.
In the platform, buttons can be configured to switch these outputs. The switching behaviour depends on the configured communication interval and the customer setup.
Once the installation is known, the logical names of the outputs can be changed in the dashboard. For example, DOUT1 can be renamed based on what it controls.

Attention!

A digital output should not be used as a direct power supply for a device.

Use the output to switch a relay or another suitable switching component.
