Product Overview | 8351 Furnace Pressure Controller
SPECIFICATIONS
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.
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. Size: 1⁄8 " DIN horizontal, 2.10" H × 3.95" W × 4.00" D. Panel Cutout: 1 25⁄32 " × 3 5⁄8 " ( 1⁄8 DIN) Weight: .32 lb. Protection Class: NEMA 4X
Furnace pressure control is generally used to maintain a slightly positive pressure, providing:
— improved product quality — maintenance savings by preventing excessive fluing through cracks and doors and also reduces "stingers" — elimination of cold air infiltration, preventing load cold spots — prevention of furnace atmosphere contamination The 8351-C-C-2013 input is fully configurable to match any input scaling requirements. • An optional 24 V dc power supply is available NOTE: When replacing an EPIC II controller, an external 24 V dc power supply is required.
