(sold separately) shown actual size.
The DRSL-SP2 isolated signal
conditioner/splitter provides a
competitive choice in terms of both
price and technology for galvanic
isolation of process voltage or
current signals to SCADA systems
or PLC equipment. Two process
outputs are provided which mirror
the single process input.
The DRSL-SP2 can be used for
signal conversion of standard
process voltage or current signals
into two individual analog signals.
The unit offers 4-port isolation,
provides surge suppression and
protects control systems from
transients and noise. The
DRSL-SP2 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. Factory calibrated
measurement ranges are easily
configured via DIP switches. When
the input is configured for
transmitter mode, the DRSL-SP2
provides the current loop supply
voltage. The unit operates over a
wide temperature range from
-25 to 70°C (-13 to 158°F).
