Data Sheet

12 Inch 1 & 2 Pen Recorder/Controller

DESCRIPTION

The MRC 8000 incorporates numerous refinements
over its 10˝ MRC 7000™ sibling, including a larger 12
inch recording area; an advanced platen assembly
which eliminates slide wire feedback for improved
reliability; as well as the incorporation of optional
isolated 4–20mA outputs to provide the highest
resolution and accuracy available in a recorder of
this type.

The MRC 8000 is offered in two versions: a basic
recorder and a recording controller. Both may be
specified as either single pen or dual pen units. Each
version is capable of measuring, recording and
displaying temperature, pressure, level, flow and
other process variables. The MRC 8000 includes
isolated universal inputs and a list of optional capa­bilities including: transmitter power supply, 5A relay
outputs, auxiliary inputs for remote setpoints, RS-485
