sames
FEATURES
+ Compatible with SA4102A / SA2002E / SA2002H /
SA2002P / SA2002D / SA2102D. All devices are PDIP20,
except for the SA2002P which is PDIP16.
+ Connection of external sensing elements, mains and
power supply by means of screw terminals.
+ Operation from either single +5V supply or dual rail supply
(20mA).
+ Direction and pulse output indication by means of on-board
LEDs.
+ Current sensing via shunt or CT (on-board termination
resistor).
+ Counter and stepper counter connections by means of
screw terminals.
+ On-board precision calibration either by analog trimpot or
digital Eeprom.
+ Direct connection to micro-controller.
+ Optically isolated output for connection to test equipment.
+ Easy accessible test pins
INTRODUCTION
The PM4100AD evaluation module is designed to demonstrate
the functionality of the following devices SA4102A, SA2002E,
SA2002H, SA2002P, SA2002D and SA2102D. The module is
easily configured and setup for the various devices by means of
on-board jumpers. The setup of the module is simplified with the
help of the accompanying software that illustrates the jumper
positions for each device.
The measured energy is displayed on an on-board LED
(PULSE), while a stepper motor counter or impulse counter can
be connected to the screw terminals provided. A second LED
(DIR) is used to indicate the energy direction.
This application note should be used in conjunction with each
device's specific datasheet for the individual device
specifications and characteristics.
