Description
NE-SPL-48 is a RS-485 over power line transceiver for powered device side with on-off keying (OOK)
modulation and demodulation function built in design for data communication line together with dc power feed.
Modulating data onto twist pair lines allows dc power delivery and data communication to share a
common pair of twisted wires,In resulting for significant reduction of the system installation cost.
NE-SPL-48 transforming OOK signals and split the DC power form data line. OOK modulation operates with immunity to data polarity for ease of system installations. The DC out put with polarity rectifier for DC+ and DC- no matter the data wiring pairs polarity.
The DC power can be galvanic isolated by built in DC/DC or Direct output the DC voltage delivered
from NE-SPL-48.
*NE-INS-48 and NE-SPL-48 need to be used together
