PD659-1MA-1MA

Signal Isolator

PD659-1MA-2MA Splitter

The Splitter splits the 4-20 mA output from the

PD765 meter into two isolated 4-20 mA outputs.

(Enclosure / meter sold separately)

FEATURES

OVERVIEW

The PD659 series includes DIN mountable models for
signal isolation, splitting and conditioning of 4-20 mA
and 0-10 VDC signals. As signal isolators, they provide a
convenient way to isolate the input signal from the power
source and output signal. As splitters, they split one
4-20 mA input into two isolated 4-20 mA outputs. As signal
conditioners, they convert either a 4-20 mA input to a
0-10 VDC output or a 0-10 VDC input to a 4-20 mA output.
