Solenoid Valve
Module (SVM)
This package
includes a solenoid
valve and a flow
adjustment valve
with all of the parts
required to assemble
an automatic system
to control the flow of
coolant thru a cooling
coil in any reactor. It
plugs into the cooling
output socket on the
4848. It is designed
for use with tap water
as the cooling media.
Communications
Software
Software is provided with
each 4848 Controller to provide
bidirectional communications
between the controller and an
attached PC. All operating set
points and control parameters
can be sent from the PC to all of
the operating modules installed
in the 4848 Controller. All data
gathered by the modules of the
4848 is transferred to the PC for
display and logging.

4838 Controller
The 4838 Controller has
been added to the line of Parr
Controllers. This controller is
intended to control the tempera-
ture in our line of non-stirred
pressure vessels. No provision is
made for the current or future
expansion to control motor stir-
ring speeds.
The controller contains the
same Temperature Control Mod-
ule used in the 4848 Controller
and provides identical control
and communications capabilities.
The high low heater feature as
well as the lock out relay and re-
set for over temperature protec-
tion are also included.
The 4838 Controllers can be
enhanced with the addition of
either a Pressure Display Module
or a High Temperature Cut Off
Module. The External Tempera-
ture Limit Module can be substi-
tuted for the High Temperature
Cut Off Module.
