Sporlan 953580 Interface Board

The 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 models, allowing contractors to standardize their service stock. It is compatible with a wide range of Sporlan components, including CDS evaporator control valves, SDR electric discharge bypass valves, and SEI, SER, and SEH series valves. Technicians can optimize performance via onboard DIP switches to adjust valve stroke and resolution, ensuring seamless integration with existing building automation systems and external controllers.

Key Benefits

• Universal Compatibility: Serves as a 952956 replacement and supports older Sporlan IB series hardware, reducing inventory overhead for service fleets.
• Versatile Signal Input: Industry-standard 4-20mA and 0-10VDC support ensures the board interfaces with virtually any modern system controller.
• Enhanced Diagnostics: Integrated LED status indicators provide immediate visual feedback on power status and valve positioning for faster troubleshooting.
• Precision Control: Features configurable pulse rates up to 400 pulses per second (pps) for high-resolution refrigerant metering and improved system efficiency.
• Application Flexibility: Directly manages complex unipolar or bipolar step motor signals for electric expansion valves (EEVs) and pressure regulators.

Common Questions Is the Sporlan 953580 a drop-in replacement for the 952956? Yes. The 953580 IB-G is the official direct replacement for the obsolete 952956 (IB-3) board. It maintains the same mounting footprint and wiring logic while adding expanded valve compatibility. What power supply is required for the IB-G board? The board requires a dedicated 24VAC (Class II) power source. It is critical for technicians to use a transformer sized appropriately (typically 30-40 VA depending on the valve load) that is not shared with other high-draw components to prevent electrical noise. How do I configure the 953580 for different valve types? Configuration is handled through a bank of eight DIP switches located on the board. These switches allow you to set the specific step count (e.g., 1596, 2500, 3193, or 6386 steps) to match the internal motor of the valve being controlled.
