BASO C664ABA-1C Module

The BASO C664ABA-1C is a mission-critical 24V intermittent pilot ignition control engineered for precision gas flow management in commercial and residential heating systems. Designed as a rugged electronic spark ignition module, it features a single-try ignition sequence with an 8-second Trial for Ignition (TFI) period. Technical professionals rely on this module for its seamless integration into existing 100% shut-off applications, ensuring safe operation by closing the main gas valve if a flame is not detected within the designated window. This unit serves as the direct replacement for BG1600M10EM-1AD and the G770KHA-2 ignition control, simplifying field service by matching legacy footprints and wiring configurations. The solid-state circuitry provides high resistance to vibration and thermal cycling, maintaining reliable flame rectification across a wide range of ambient conditions. Whether servicing HVAC gas furnace controls or industrial boilers, the C664ABA-1C ensures stable sequence timing and consistent performance across the entire HVACR ignition sequence.

• Direct-Drop Replacement: Engineered to replace obsolete BG1600M10EM-1AD and G770KHA-2 units without complex bracket modifications.
• Optimized TFI Timing: The 8-second Trial for Ignition provides adequate window for pilot stabilization while maintaining safety protocols.
• Intermittent Pilot Operation: Enhances energy efficiency by eliminating the need for a standing pilot light.
• Standardized 24VAC Input: Compatible with common HVACR control transformers and 24V thermostat circuits.
• Integrated Safety Shut-off: Provides 100% shut-off of gas flow upon flame failure or failed ignition attempt.

Is the BASO C664ABA-1C compatible with 120V systems?
No, this module is rated for 24VAC control circuits only. Applying 120V will result in immediate failure of the internal solid-state components.

Can I use this to replace a continuous retry module?
This is a single-try ignition module. If the application requires multiple attempts before lockout, verify local codes and appliance specifications before substituting.

How do I troubleshoot a flame sensing issue with this module?
Verify that the flame sensor is positioned correctly in the pilot flame and that the module has a solid chassis ground. Check for a minimum of 0.7 microamps DC through the flame rectification circuit.
