Sporlan 953580 Interface Board 318518-761 5 inches WC but remains

5 inches WC but remains adjustable from 3 to 5 inches WC to ensure precise manifold pressure during commissioning

External Equalization: Provides improved response time and sensitivity compared to internally equalized models for complex piping layouts

Reduced Maintenance: Precise balancing minimizes mechanical vibration

The 30-inch insulated leads provide the necessary reach for standard high-voltage control boxes

Direct Coupled Design: Streamlines installation and reduces mechanical failure points by removing external linkages

Sporlan 953580 Interface Board 318518-761 5 inches WC but remainsThe Sporlan 953580 Interface Board, also known as the IB G Control Board, is the advanced technical successor for the discontinued Sporlan 952956. Developed for precision refrigerant flow management, this HVAC interface module converts 0 10VDC or 4 20mA analog input signals into digital step motor pulses to drive electronic expansion valves. As an all in one replacement, the 953580 consolidates the functionality of previous IB 1, IB 2, IB 3, and IB 6
