CZ2031 is a DIN‑rail mounted analog signal isolator, supporting 4‑20mA HART signal input and output. It adopts galvanic isolation to eliminate ground loop interference between field transmitters and control system. Power supply range is 20‑30V DC, working temperature from ‑20℃ to +60℃. Compact thin‑type housing for cabinet installation, widely used in marine and industrial automation systems for signal isolation, conversion and transmission of pressure, level and temperature sensors.
