1~DESCRIPTION
.
The
SEM1600B is a powered bridge amplifier for use with strain
gauges or load cell signals. The product has a built-in capability to
scale the input signal to a process value while the output stage offers
either voltage, bipolar voltage or active/passive current retransmission
signals. The device uses ratio metric measurement to obtain high
stability.
The
product comes with an AC/DC power supply that will operate in
the range (10 to 48) VDC and (10 to 32) VAC making the device ideal
for battery operation. An additional volt-free contact input is available
for tare setting using a remote switch. The high precision input stage
of the device allows for a bridge excitation voltage of 5 VDC to be
used, as opposed to the traditional 10 VDC. This reduces the power
requirement for the bridge supply and up to four bridges (cells) may
be connected to the input
.
To
configure: connect a standard USB cable between the SEM1600B
and a PC. The free configuration software will guide you through any
changes you wish to make. The SEM1600B does not need to be
wired to a power supply for configuration.

4~INSTALLATION AND WIRING.
Important safety requirements
This
equipment is suitable for Environment Installation BS EN61010-1
Pollution Degree 2; Installation CAT II; CLASS I and is classed as
"PERMANENTLY CONNECTED EQUIPMENT". The equipment is
intended for industrial and commercial application only and is not
suitable for domestic or medical use.
The
equipment must be mounted inside an enclosure that provides
protection >= IP65. In NORMAL USE, the equipment will only be
accessed for maintenance by qualified personnel.
Please
ensure the equipment is mounted vertically with terminals (10,
11 and 12) at the bottom. This will provide maximum ventilation.
This
equipment may generate heat. Ensure the enclosure size is
adequate to dissipate heat. Be sure to consider any other equipment
inside the enclosure.
The
equipment surfaces may be cleaned with a damp cloth. Use a
mild detergent/water. Ensure the supply is off before cleaning and, on
completion of cleaning, the equipment is completely dry before the
supply is turned back ON.
This
equipment must be installed by a qualified person. All electrical
wiring must be carried out in accordance with the appropriate
regulations for the place of installation.

STATE
The
equipment must be mounted on a DIN rail style DIN EN50022
inside a plastic or metal enclosure with a protection level >= IP65. All
wiring must be secured. Maximum cable sizes 2.5 mm². Connection is
via screw clamp terminals.
4.2~ELECTRICAL/CONNECTIONS
For
wiring connections refer to the side label on the SEM1600B and
this document.
Supply
(10 to 48) Vdc, (10 to 32) Vac
To
maintain CE EMC requirements, input and supply wires must be
less than 30 metres.
Input
cable lengths > 3 m it is recommended to use screened or
twisted pair.
Maximum
mA output cable run = 1000 metres. The output loop
should be grounded at a single point.
Before
installation, care must be taken to ensure enough voltage is
available in any loop to drive the total loop load.
