The DRSL-SP1 isolated repeater/
splitter provides a competitive
choice in terms of both price and
technology for galvanic isolation of
current signals to SCADA systems
or PLC equipment. Two current
outputs are provided which mirror
the single current input.
The DRSL-SP1 can be used for
signal conversion of a standard
process current signal into two
individual analog signals. The unit
offers 4-port isolation, provides
surge suppression and protects
control systems from transients
and noise. The DRSL-SP1 also
eliminates ground loops and can be
used for measuring floating signals.
Low power consumption facilitates
DIN rail mounting without the need
for any air gap. Measurement
ranges are factory calibrated.
The unit operates over a wide
temperature range from -25 to 70°C
(-13 to 158°F).
