Bard HVAC 8201-123BX Solid State Relay
The Bard HVAC 8201-123BX Solid State Relay is an electrical switching device found in many Bard HVAC equipment models, including the W48A2, W60A2, W72A2, W84A2, W96A2, and W120A2. It acts as a switch, directing the flow of electricity to various HVAC components based on signals received from the thermostat or other control systems. Unlike typical mechanical relays, SSRs use an electronic signal to activate the switch, which provides various advantages. The Bard 8201-123BX SSR is a single-pole, double-throw switch, which means it can control the flow of electricity to one of two output circuits. It has a rated load current of 20 amps, a maximum voltage of 277 volts AC, and an LED indicator to indicate its working state.
