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, enabling direct switching of pumps, solenoid valves, and alarms without external interposing relays.
This module allows the 9900 transmitter to drive high-power AC/DC loads—including dosing pumps, purge valves, and audible/visual alarms—with adjustable hysteresis and time delay configured via the ¼-DIN display. This eliminates the need for external interposing relays in pH, conductivity, flow, and dosing control loops.
