Maxitrol A1092 Amplifier

Upgrade your industrial or commercial heating system with the Maxitrol A1092 Amplifier, a high-performance component engineered specifically for Series 92 Selectra modulation systems. Designed for indirect fired applications, this amplifier is the standard professional choice for technicians seeking precise gas flame modulation and high single-stage turndown ratios. Unlike the A1094 model which uses ribbon cables, the Maxitrol A1092 utilizes a robust 4-wire configuration for connecting to TD92 remote temperature selectors, ensuring reliable signal integrity over distances up to 300 feet. It is fully compatible with M420, M520, and M620 modulating valves, providing instantaneous response and continuous pressure adjustment without the mechanical lag of mod motors. Operating on a 24 VAC Class II transformer, this rugged unit maintains stable discharge air temperatures in harsh environments. Whether you are performing a field retrofit or specifying a new HVAC burner control setup, this Maxitrol Series 94 amplifier delivers the technical consistency required for high-demand industrial process control and commercial air handling units.

• Enhanced Modulation Precision: Specifically optimized for indirect fired burner systems to achieve superior temperature stability and high turndown.
• Simplified Field Wiring: Uses standard 4-wire connections rather than ribbon cables, allowing for easier maintenance and long-range sensor wiring up to 300 feet.
• Broad System Compatibility: Seamlessly integrates with Maxitrol M-Series modulating valves (M420, M520, M620) and 1,000 ohm RTD sensors like the TS394.
• Rugged Industrial Build: Designed to withstand demanding mechanical room environments with a compact footprint and reliable 24V power modulation.
• Optional Temperature Override: Supports the T115 room override thermostat for flexible space temperature control when used with remote selectors.

What is the main difference between the A1092 and the A1094 amplifier?
Technicians prefer the Maxitrol A1092 for its 4-wire terminal block connection, whereas the A1094 uses a ribbon cable. This makes the A1092 ideal for field installations where standard wiring is already present or preferred for durability.

Which sensors should be used with the A1092 for duct temperature sensing?
For accurate discharge air monitoring, we recommend using a 1,000 ohm RTD, such as the TS394-3B-48FQ or a TS194 sensor equipped with a mixing tube to ensure the amplifier receives a stable reference signal.

Can the A1092 handle different power frequencies?
Yes, the Maxitrol A1092 is designed to run on a 24 VAC, 40 VA independent transformer and is compatible with both 50 Hz and 60 Hz frequencies, providing versatile application across different regions.
