Honeywell RP418A1073 Electric Pneumatic Relay 277V/60Hz

The Honeywell RP418A1073 Electric-Pneumatic Relay is used in HVAC systems to control pneumatic actuators with the help of electrical signals. It runs at 277V/60Hz and takes an electrical input to provide a pneumatic output for the control of pneumatic dampers and valves. When an electrical signal is received, the relay opens an internal valve, allowing compressed air to be supplied to the pneumatic part such as a damper actuator. This precise control is useful when controlling the flow of air in HVAC systems, as well as potting temperature range for energy conservative and the comfort of building occupants. Some of the uses include the regulation of dampers in air handling units and variable air volume boxes.
