INTRODUCTION
The QSB and QSI modules are
available with or without a display.
The QSI modules are also available
as a “display ready” version with
no display installed, but ready for
the customer to install his own GPI
display.
QSB:
The QSB module is equipped with
pulse-out electronics. Pulse out
electronics is the default standard
regardless of type of module or
style of cover plate. This manual
contains information and meter
wiring diagrams for the QSB pulse-
out electronics.
QSI:
The QSI communications module
is a multiple capability electronics
package and has three versions
(QSI1, QSI2 or QSI3) available; each
with its own mix of capabilities to
better serve the customer (See
Versions below).
• QSI1 is equipped with:
Bluetooth®, **coil/digital pulse
input, pulse output (flow or energy
& scalable), RS485 (Modbus®
RTU), temperature inputs, BTU
calculator.
• QSI2 is equipped with:
Bluetooth, **coil/digital pulse
input, pulse output (flow or
energy & scalable), data logger,
temperature inputs, BTU
calculator.
• QSI3 is equipped with:
Bluetooth, **coil/digital pulse
input, pulse output (flow scalable),
data logger, 4-20mA output.
This manual contains information and
meter wiring diagrams for the three
different QSI electronics modules.
IMPORTANT NOTICE
QSB and QSI module electronics
are very sensitive to electric noise
if operated within 6 inches of some
electric motors, relays, transformers
or other sources of electronic noise.
If the QSB or QSI electronics are
used in a manner not specified by
the manufacturer, the protection
provided by the equipment may be
impaired.
GENERAL INFORMATION
QSB and QSI electronics are
available factory installed on
designated meters, or as modules
that will adapt the electronics to
other GPI meters.
The QSB and QSI electronics
converts the voltage (or pulses) from
the meter into usable information
to support the various capabilities
of the modules. The modules also
supply the display (when installed)
with the information and power it
needs to function as designed.
The QSB and QSI module electronics
are powered by customer- supplied
external power.
