APPLICATION
PLASTICS EXTRUDER APPLICATION
temperature of a plastics extruder. Each T48 controls a
heating element and a cooling water solenoid to maintain
each extruder zone at the desired temperature. The Heater
Current Monitor option is used to provide a readout of the
heater current. The multi-function User Input can be
programmed to allow selection of manual operation when
connected to common. This allows the user to hold the
control output of the controller during abnormal process
conditions.
MULTIPLE UNIT/REMOTE SETPOINT APPLICATION
within the oven. Depending upon the material to be dried, and its initial
moisture content, the drying setpoint temperature varies. A master T48
controller transmits setpoint via linear DC output. This signal is received as
a remote setpoint signal by the other slave controllers.
Several T48 controllers are employed to control the
Eight T48 controllers are used in a drying oven. Each T48 controls a zone

OEM PAINT SPRAYER APPLICATION
the T48 to maintain optimum paint temperature. In addition to
the low cost, the 1/16 DIN package size permits the OEM to
design temperature control into various sized painting
equipment, from small hand sprayers to large paint booths. The
heating element used to heat the paint, is connected to the Main
Control Output (OP1) programmed for On/Off control. Alarm 1
is programmed as Band Inside Acting, so that as long as the
paint temperature is within manufacturer’s specifications for
temperature, the “GO” light is on. Alarm 2 is programmed as
Band Outside acting so that the “NO GO” light is lit when the
paint temperature is more than 12° outside the manufacturer’s
specifications of 140 to 150°F.
