and includes a 7 digit LCD driver with
announciators
! 4 externally selectable on-chip tariff reg-
isters
! An additional total energy register
! Meets the accuracy requirements for
Class 1 AC Watt hour meters
! Optical interface for electronic reading
according to IEC1107 Mode D
! Pulse output for calibration
! Total power consumption rating below
100mW
! Uses current transformers for current
sensing
! Operates over a wide temperature range
! Demonstration software included
DESCRIPTION
The SAMES monochip three phase bidirectional kilowatt hour metering module, the
PM9110BF, provides all the required metering functions including energy measure-
ment, a 7 digit LCD driver, a tariff selection facility, an optical port as well as a pulse
output for calibration purposes.
Energy consumption is determined by the power measurement being integrated over
time.
This method of calculation takes the power factor into account.
This application utilises the SAMES SA9110AFA monochip three phase bidirectional
kilowatt hour metering IC for energy measurement.

Note: The recommended connections above are applicable for the demonstration
software provided with the PM9110BF.
6. Optical Port
The optical port has been designed to meet the IEC1107 Mode D specification. This
facillity offers a pulse output as well as a serial data meter reading facility.
Three types of interfacing elements from the PM9110BF are available:
a) Infra-red optical port
b) Red LED
c) Opto-coupler
In order to maximise the intensity of the element, it is suggested that only one of
the outputs be used at any one time.

7. Liquid Crystal Display (LCD)
The PM9110BF has a LCD comprising of seven digits with announciatiors.
To cater for compatibility with future devices four jumpers are provided for
backplane driving configurations. The PM9110BF boards are shipped to the
customer with jumpers in a default configuration.
8. Tariff, Scroll and Reset Functions
Tariff Selection
A dual DIP switch provides the user with the facility to set the active tariff register
in which consumption will be accumulated.
The active register is indicated on the LCD.

Detail
Note 3
Note 3
Note 1: Resistor (R8, R9, R10, R11, R12 and R13) values are dependant upon the selected
values of the current transformer termination resistors R18, R19 and R20
Note 2: Capacitor values may be selected to compensate for phase errors caused by
the current transformers
Note 3: Capacitor (C13) to be positioned as close to Supply Pins (VDD & VSS) of IC-1, as
possible
Note 4: See the table below detailing the component values for the selected voltage
standard
