Pneumatic Electric Relay

ensuring precise fuel-to-air ratios for consistent combustion across all heating cycles

making it an ideal choice for service calls involving low-voltage thermostats

It remains a liquid within the sealed system and only polymerizes at the site of a leak when it reacts with external moisture and differential pressure

it is intended for indoor use or must be housed within a NEMA-rated enclosure to protect the surface mount timer from environmental exposure

Honeywell MS7510A2008 Actuator Els PW 17895 Pneumatic Electric RelayThe Honeywell MS7510A2008 Actuator is a spring return direct coupled actuator (DCA) engineered for precise control of HVAC dampers in commercial air handling systems. This unit provides 88 lb in torque and is designed to accept multiple control signals, including 0 2 10 Vdc, 4 20 mA (via the included 500 Ohm resistor), floating, and on off SPDT. Operating on a 24Vac Dc power supply, it features a self centering clamping adapter that accommodates 3 8"
