FA-TC9102-0221

The Johnson Controls FA-TC9102-0221 is a Direct Digital Controller primarily designed for HVAC applications. It ensures precise temperature regulation through its proportional control capabilities, which operate through a voltage range of 0 to 10 VDC. Fan control is managed via an On/Off relay, enabling users to maintain optimal airflow as needed.

The device's operational range makes it suitable for environments with temperatures from 32°F to 122°F (0°C to 50°C) and can handle relative humidity conditions of 10% to 90% without condensation affecting performance. Communication features include an opto-isolated N2 bus, contributing to operational integrity within a larger system of controllers.

Connections for input and output are facilitated via screw terminal blocks, simplifying the wiring process for integration into existing setups. The active 3-wire configuration for remote setpoints can accommodate pots in the 0 to 10K ohm range, facilitating adjustments from a distance.

For output control, the heating and cooling requirements are managed through a triac with a capacity of 0.5A at 24V AC, ensuring reliable operation in various conditions. Additionally, fan control employs a relay rated at 3A for voltages between 125 to 250 VAC, capable of handling a maximum motor rating of 1/8 horsepower. Overall, the FA-TC9102-0221 Direct Digital Controller is equipped to efficiently manage heating, cooling, and ventilation systems.
