The energy meter is equipped with two pulse outputs (forward and reverse)
which are optically isolated from the inside circuit. It generates pulses in
proportion to the measured consumption for purpose of remote reading or
accuracy testing. The pulse output is a polarity dependent, open-collector
transistor output requiring an external voltage source for correct operation.
For this external voltage source, the voltage (Ui) should be lower than 27V
DC. The maximum switching current (Imax) is 100mA. To connect the impulse
output, connect 5-27V DC to connector 18/20 (collector), and the signal wire
(S) to connector 19/21 (emitter).

Appendix 3 – Modbus version
A3 .1 Communicating via the Modbus output
The meter can communicate with your PC. In order to read out the meter
registers first install and configure the PC software. Use an RS485 level
converter to connect the PC and the meter. The cable should be connected to
terminals 22 and 23. The default communication address of the meter is 01. The
PRO380-Mod can be connected for Modbus communication. The Modbus
implementation used is Modbus basic (standard). This means the following:
· Baud rate 9600 · 8 data bits · Even parity · 1 stop bit The baud rate can be
lowered to values 4800, 2400, 1200, 600 and 300. The parity can be set to none
or odd. Data and stopbit cannot be changed.
When connecting the meter through a serial converter (RS485) for testing,
please be aware that because of not implementing the complete Modbus
infrastructure, there will be a need to put an additional resistor (120 ohms/
0,25 watts) across the terminals (22 & 23) on the meter side. For the
registers used in the meter and how to interpreted the data, please use the
Modbus register map on the next pages. More info on Modbus can be found:
