1 Safety instructions
Additional regulations
These operating instructions contain the most important notes for operating the
in-line measuring amplifier (ILA) and the industrial power injector (GTM-PWIN)
safely. Consideration must also be given to the legal and safety regulations
applicable at the operating location, the accident prevention regulations
applicable at the operating location and the technical data in connection with the
safety regulations listed here.
Particular hazards
DANGER
Fatal hazard due to electrical current!
The devices are operated with electrical current; there is therefore
always a risk of an electric shock.
Therefore: keep the devices away from rain, moisture and heat
sources.
DANGER
Damage to the device due to an incorrect power supply!
An incorrect power supply can lead to damage at the industrial
power injector (GTM-PWIN).
Therefore: use the industrial power injector (GTM-PWIN) exclusively
with power supplies, that comply with the technical specifications.
DANGER
Damage to the device due to an incorrect power supply.
The in-line measuring amplifier (ILA) is supplied exclusively via Power
over Ethernet (passive).
Therefore: use the ILA exclusively with the GTM power injector
(PWIN) or another industrial, passive power injector that complies
with the technical specifications.

Residual hazards
The measuring amplifier (ILA) and the power injector (PWIN) are state-of-the-art
and safe to operate. Residual hazards can arise during operation if the devices are
used and operated improperly by unqualified personnel.
The scope of supply of the measuring amplifier (ILA) and the power injector (PWIN)
only covers a partial area of mechatronic metrology. The safety aspects when
using the in-line measuring amplifier (ILA) and the power injector (PWIN) in an
overall system must be taken into consideration by the system designer, the
outfitter and/or the operator so that residual hazards are minimised. The residual
hazards remaining in the overall system must be pointed out.
Condition and changes
The in-line measuring amplifier (ILA) and the power injector (PWIN) may only be
operated in flawless condition subject to compliance with the notes described in
the operating instructions. Neither the design nor the safety technology of the
devices may be modified.
Personnel qualifications
The in-line measuring amplifier (ILA) and the power injector (PWIN) must only be
installed and operated by qualified personnel.
Qualified personnel refers to persons who are familiar with the installation,
commissioning and operation of the devices and who have qualifications
corresponding to their work.
Ambient conditions
The in-line measuring amplifier (ILA) and the power injector (PWIN) are intended
for use in industrial applications subject to adherence to the ambient conditions
specified in the technical data.
Protect the devices from the effects of weather such as rain and snow.
Implement suitable measures on site to protect against overvoltage, e.g. due to
lightning strikes.

Storage and transport instructions
The in-line measuring amplifier (ILA) is a precision measuring instrument that must
accordingly be handled with care.
Dropping and shocks can cause damage to the measuring amplifier, therefore
prohibiting its continued use.
Use the original transport packaging or other suitable custom packaging for
storage and transport.
Excepted use
Any use of the in-line measuring amplifier (ILA) and the power injector (PWIN) that
exceeds the scope of proper use and/or any alternative use can lead to hazardous
situations.
The devices are not safety elements. They may not be used in an overall system if
their failure can lead to the endangerment of persons.
The devices may not be used in the context of legal metrology.
The devices are not suitable or approved for use in potentially explosive
atmospheres.

3 In-line measuring amplifier ILA
3.1 Product description
The in-line measuring amplifier ILA is a high-performance, single-channel strain
gauge full bridge measuring amplifier. Strain gauge-based transducers and sensors
such as e.g. force and torque transducers, load cells [kg or N], etc. can be
connected to the ILA on the sensor side.
The ILA is configured entirely via the EtherCAT® interface1) in the application
control system. The corresponding device description file ESI (EtherCAT Slave
Information) is made available for system integration. The ESI is available for
downloading from the ILA product page. www.gtm-gmbh.com/produkte/dms-
messverstaerker/messverstaerker-serie-ila
Voltage is supplied via passive Power over Ethernet and RJ45 network cables. The
GTM power injector ILA-PWIN or other suitable passive power injectors are
required for this.
Depending on application or the number of channels, several ILAs can be
connected in a line using a daisy chain. The voltage is always supplied via the
industrial GTM power injector or other suitable passive power injectors.

3.2 Installation/connection
The in-line measuring amplifier (ILA) is essentially suitable for sensor-near
operation and can be installed flexibly in all directions in your application (subject
to adherence to technical specifications). Depending on the layout of your
application, the following installation types can prove sensible:
1) EtherCAT® is a registered trademark and patented technology licensed by Beckhoff Automation GmbH,
Germany.

#PrecisionWins www.gtm-gmbh.com
SThe ILA is fastened in the housing of your application using the four fastening
holes (through holes).
SIn applications involving multiple channels, the ILAs can be coupled together
using connectors on the lower side. Additionally fastening the ILAs to one
another using M4x60 screws (e.g. Allen or other screws) is recommended. This
configuration may be sensible depending on application. Check whether and
how the lowest ILA is fastened using the M3 hole on the lower side if necessary.
SThe ILA has an M3 hole on the lower side of the housing. This hole can be used
e.g. to fasten a DIN rail mounting clip (e.g. Farnell DNC-4796). This enables the
ILA to be mounted easily and flexibly on classic top-hat rails.
NOTE
In your layout, make sure that the ILA is installed so that the
technical specifications for connectors and connecting cables are
adhered to, particularly in the event of operation in harsh ambient
conditions. E.g. no standing fluids on the connection sockets, etc.
Connections
The ILA has a total of three connections:
SOne M12 connection for the strain gauge transducer (see Tab. 3.1, Page 11)
STwo RJ45 connections that carry both the EtherCAT® signal from your control
system and the supply via Power over Ethernet (PoE) (see Tab. 3.2, Page 12)
- IN: input (control system and supply), on use with one in-line measuring
amplifier
- OUT: output (via integrated switch), on application with several ILAs in a line
structure.
Pin assignment of both connection sockets, see Chapter 3.2.2.
