MAMAC Systems EP-321 Tristate Pneumatic Transducer Freon The FM55 is a 3-legThe MAMAC Systems EP 321 is a high performance tri state to pneumatic transducer designed for precise HVAC pneumatic control. This unit effectively bridges the gap between digital controllers and pneumatic actuators by converting a 24VAC VDC tristate signal into a stepped pressure output. Engineered for reliability in building automation systems, the EP 321 features a 0 20 PSIG output range and a sophisticated pulse train mechanism that allows any
