Description
The Honeywell RP670B1074 Pneumatic Switching Relay that is made for HVAC Systems. It functions at pressures ranging between 20 and 25 PSI, by using this pressure difference to manage the airflow in two distinct circuits. The switching action of 2-SPDT makes it possible for the relay to control two circuits at once, making it possible to control sequences in the HVAC system. This relay is essential for the execution of other control functions like changing the heating and cooling modes, controlling the dampers for air flow and other pneumatic parts.
