The 8351 Furnace Pressure Controller, in conjunction with a
dp transmitter, provides stable furnace pressure and manual/
automatic station functions.
8351-C relay outputs are used to drive interposing relays which
can interface with a variety of output actuators such as electro-
hydraulic valves, solenoid valves, or bi-directional motors.
A second 4-20 mA PID output is also included to position a
4-20mA control motor or linear actuator.
Furnace pressure control is generally used to maintain a
slightly positive pressure, providing:
—
improved product quality
—
maintenance savings by preventing excessive fl uing
through cracks and doors and also reduces "stingers"
—
elimination of cold air infi ltration, preventing load cold
spots
—
prevention of furnace atmosphere contamination
The 8351-C-C-2013 input is fully confi gurable to match any input
scaling requirements.
Operating Temperature Range:
0 to 149°F (–18 to 65°C).
Power Requirements:
120 V ac 50-60 Hz (102-132 V ac) at 15 VA
exclusive of connected load.
Output Load Limits:
1.2 amps maximum at 120 V ac; 50 mA
minimum.
