Description
The Maxitrol SC11S-B Signal Conditioner is a track-mounted control accessory designed for use with Selectra Series modulation valves and gas control systems. This conditioner accepts standard 4-20 mA or 0-10 VDC input signals from thermostats, sensors, or controllers and converts them to a controlled 0-20 VDC output suitable for driving one or more modulating gas valves and controls. Built to Maxitrol signal conditioning specifications, it features user-configurable input selection and can include a low-fire start timer for controlled valve sequencing. Ideal for HVAC technicians, system integrators, and controls installers, it enhances system responsiveness and improves signal compatibility between controllers and field devices. Reliable conditioning of control signals helps support proper combustion modulation and stable operation in varied HVAC applications.
