The Smartlink24 Pulse Splitter is designed to split pulses from meters or turbine units, into two separate outputs. Two versions available - Battery - Power Our Pulse Splitter is an OPEN collector meaning that it drops to ZERO pulse. Most BMS systems start working at 2 Volts and most Chatterboxes only start reading at 5 volts. This causes problems when connecting to the BMS system, as they will not read the meters. Smartlink24 works on a low Voltage and the open collector starts from 0.001 Our Pulse Splitters read your meters.....EVERYTIME.
