The model DRI-SP-DC is a DIN rail mount,
4 to 20 mA signal splitter, with 2000 Vac isolation
between input,output and power. It provides two fully
isolated 4 to 20 mA outputs in proportion to a single
4 to 20 mA input. Front accessed zero and span
potentiometers allow 50% adjustment of offset and
gain to compensate for sensor errors or signal losses.
The DRI-SP-DC features plug-in screw terminals
for easy installation. Two or more modules can slide
together and interlock for solid, high density mounting
(remove either the DIN rail foot or the adjacent
unit’s faceplate, for right side or left side mounting,
respectively). The module to be attached will easily
slide onto the side of the mounted unit.
DC input four-wire transmitters are used to isolate
and convert DC signals into proportional, standard
industrial control signals. Typically an industrial control
system such as a DCS or PLC requires standard
industrial control signals with full isolation to ensure
reliable, strong signals.
In most industrial process control or data acquisition
applications, several different input sources from
various field instruments (e.g. level, flow, pressure and
position sensors), are common. Four-wire transmitters
accept these field inputs and provide the controller
(DCS & PLC) with the standard industrial signal it
requires. The four-wire transmitter will increase the
signal drive to high impedance loads and may improve
resolution of the process variable. The DRI-SP-DC
operates as a four-wire transmitter and derives its
power from an independent, transformer isolated DC
power source (10.8 to 26.4 Vdc).
