Linearized
and isolated RTD and Thermocouple transmitters
are part of the Series SC4000 Iso Verter® II Signal Conditioning
Modules. These modules completely isolate the input from
the output and from the ground. Compatible with industry
standard 35 mm DIN Rail mount transmitters and isolators,
these modules are easily applied in new or existing installations.
The SC4380
Process Signal Converter/Isolator accepts virtually
all standard process signals as input, and isolates and
retransmits the signal in either the same units or virtually
any other standard process signal. The SC4380 can be field
programmed for reverse or direct action and can receive
and transmit single sided or bipolar* signals. Low voltage
units (SCL) are also available.
The SC4151
RTD Transmitters each offer a fixed scale range
input (selected when ordered) and a linearized, isolated,
field selectable 4 to 20 mA or 0 to 10 VDC output. Output
is selected by simple switch settings. Low voltage units
(SCL) are also available.
The SC4130
Thermocouple Transmitter offers a fixed scale
range input (selected when ordered) and a linearized, isolated,
field selectable 4 to 20 mA or 0 to 10 VDC output. Output
is selected by simple switch settings. Low voltage units
(SCL) are also available.
*Note: The term "bipolar"
refers to an input or output that crosses zero volts. Certain
devices have ranges that run from minus to plus voltages
( eg. -1 to +5 VDC, -10 to +10 VDC, etc.). The SC4380 Iso
Verter® II can be set up to accept bipolar signal input
or provide bipolar output.
