2.4.5 Connecting to an External Revenue Meter
SWF850 has the ability to collect external energy pulses from revenue meters of 3
rd
party. These
pulses are called “Kt” pulses which usually one pulse represents a certain amount of kWh measured
in the meter. Hence, by collecting such pulse from the meter will allow SWF850 logger to cumulate
the actual energy measured by this meter. Below shows the digital input DI connector image:
With digital input specifications in the below table:
Connector Type Screw Type Terminal
Wire Size
AWG 12-30，length of exposed copper 6-7mm
Signal Type Digital Status Contact
Signal Range
