Daikin-McQuay 910170426 SC30-SM2 Maxitrol
The Daikin-McQuay 910170426 SC30-SM2 Maxitrol is a specialized electronic signal conditioner engineered for atmospheric indirect fired heaters featuring sectioned gas manifolds and two-speed inducer motors. This OEM HVAC replacement part functions as a critical interface between a building automation system (BAS) and Maxitrol Selectra gas valves, specifically optimized for the M420, M520, and M620 series modulating valves. By converting a standard 0-10 VDC or 2-10 VDC controller signal into a 0-20 VDC output, the SC30-SM2 ensures precise modulation and peak combustion efficiency.
A veteran technician will appreciate the SC30-SM2 Maxitrol for its ability to manage complex firing sequences. It features an integrated adjustable low-fire start timer (5-55 seconds) and a dedicated SPDT inducer relay (2A max) to control inducer speeds based on the technical requirements of the heating cycle. With a 24 VAC power requirement and a robust track-mounted design, this Daikin burner control supports high-turndown applications, often achieving a 10:1 ratio. The unit’s LED status indicators provide immediate visual diagnostics for power, modulation, and relay states, simplifying field troubleshooting during commissioning or service calls.
Key Benefits- Precision Modulation: Converts 0-10 VDC inputs into actionable 0-20 VDC signals for Maxitrol M-series valves, preventing burner oscillation.
- Optimized Combustion: Includes an adjustable start-up voltage (5-15 VDC) to ensure reliable light-off even at minimum firing rates.
- Integrated inducer Control: Features a built-in relay to switch between low and high inducer speeds, eliminating the need for external timing components.
- Sectioned Manifold Compatibility: Purpose-built for split-manifold designs, allowing one section to modulate while the other operates in two-stage mode.
- Field Diagnostics: Seven status-specific LEDs (PWR, SU, R1, R2, R3, AFS, MOD) allow for rapid identification of operational faults.
What input signals does the SC30-SM2 support?
This unit is designed to accept universal controller signals, including 0-10 VDC, 2-10 VDC, 0-20 mA, and 4-20 mA, providing maximum flexibility for modern BAS integrations.
Can I use this for direct-fired makeup air units?
While the SC30 series is versatile, the SC30-SM2 is specifically tailored for atmospheric indirect fired heaters with two-speed inducers and sectioned manifolds; always verify your specific sequence of operation.
Is the startup timer adjustable?
Yes, the low-fire start timer is field-adjustable from 5 to 55 seconds, allowing technicians to dial in the perfect ignition timing for the specific burner configuration.
