The DRSL-DC2 isolated DIN
rail signal conditioner 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. The DRSL-DC2
can be used for signal conversion
of standard process voltage or
current signals. The unit offers
isolation between input, output and
supply, provides surge suppression
and protects control systems from
transients and noise.
The DRSL-DC2 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 2-wire
transmitter mode, the DRSL-DC2
provides the current loop supply
voltage. The unit operates over a
wide temperature range from -25 to
70°C (-13 to 158°F).
