Veris Industries EP2100S2 Transducer L99H008 the 1172504 supports both frequenciesThe Veris Industries EP2100S2 is a high performance electropneumatic transducer designed for precise pneumatic control in commercial HVACR environments. Utilizing advanced microcontrolled poppet valve technology, this unit converts electronic signals into proportional pneumatic outputseither 3 15 psi or 0 20 psigwhile consuming zero air when at a steady state. This eliminates internal air losses common in older flapper nozzle designs, making it an
