Plug-In Relay Expansion Module for 9900 SmartPro® Transmitter
The 3‑9900.393 is a field-installable plug-in Relay Module that adds two programmable SPDT dry-contact relays (5A @ 250VAC / 30VDC) to a panel-mount 9900‑1P base unit for pump/alarm switching.
Automation Function & Key Advantage
It lets the 9900 directly drive high‑power AC/DC loads—dosing pumps, solenoid valves, and audible alarms—with adjustable hysteresis & time delay, removing the need for external interposing relays.
