SmartPro® Single-Channel Panel-Mount Transmitter (Base Unit)
The 3‑9900‑1P is a ¼‑DIN panel‑mount multi‑parameter transmitter accepting flow, pH/ORP, cond/res, pressure, level, DO, or 4-20 mA (via 8058 iGo®). Features include one isolated 4-20 mA standard output, NEMA 4X front rating, and field-expandable capabilities via Relay/Batch/Modbus/2nd‑4-20/Cond modules.
Automation Role – Single‑Loop Control & Modular Scaling
Drives pump/valve interlocks, dosing control, and alarms on one parameter in applications including RO/DI, WW, chemical dosing, and cooling towers. Start with the base unit and add modules as the loop expands—no PLC rewrite required.
