Georg Fischer Signet 3-9900-1P Multipanel Transmitter

Georg Fischer Signet 9900 SmartPro Transmitter, model 3-9900-1P, is a single‑channel, panel‑mount transmitter that accepts one 4‑20 mA analog input (with support for frequency and S3L signals) and provides a corresponding 4‑20 mA analog output, powered from 12–24 VDC. The panel‑mount variant is identified by code 159 001 695, while a field‑mount version is 159 001 696. It features a large, backlit display with an automatic brightness function, a digital bar graph for quick trend reading, and a 13‑character labeling capability for the measurement channel, plus optional retrofittable relays for local signaling. The interface is designed to be consistent with Signet ProPoint and ProcessPro legacy devices, enabling straightforward configuration within existing GF Signet ecosystems. This transmitter is suited for process automation tasks that require reliable signal conditioning and transmission from a 4‑20 mA sensor to a control system, PLC or DCS, in environments such as water treatment, chemical processing, and general industrial instrumentation where robust, space‑efficient panel or field mounting is preferred.
