Electronic pressure regulator

Type-550X miniature electropneumatic I/P, E/P transducer converts variable current or voltage signal to proportional pneumatic pressure. Volume booster provides up to 20 scfm air flow for increased control speed. Uses 4-20 mA input signal. Standard output pressure ranges are 3-15, 3-27, 6-30, 2-60, and 3-120 psig. Zerobased output is 0-30, 0-60, and 0-120 psig. Supply pressure to 100 psig in standard and 130 psig in zero-based range.
