BL983324 TDS Mini Controllers • Large Clear LCD • Fire Retardant Casing • Splash-Resistant Cover The BL983324 is a compact, panel mounted, process controller for measuring total dissolved solids (TDS) of a process stream that is within the 0.0 to 49.9 ppm (mg/L) range. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. When in automatic mode the dry contact relay is activated when a reading is above the set point. The relay can be used to supply power to a dosing pump or a solenoid connected to a valve. The BL983324 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation. The BL983324 uses a 0.5 conversion factor in which 1.0 μS/cm = 0.5 ppm. Adjustable Dry Contact Dosing Relay The BL983324 features a dosing relay that is activated when the reading is above a user programmable set point. Programmable Overdose Protection For enhanced safety the mini controller can be programmed to deactivate the dosing relay if the set point is not reached within a specified time interval. The overdosing timer is programmable from 5 to 30 minutes or disabled. Relay Control Override With the flick of a switch the mini controller's relay can be disabled (Off), placed in control (Auto), or be activated for manual operation (On) which is useful for priming a dosing pump. Multicolor LED Indicator Multicolor LED indicator allows an operator to quickly check the status of the controller. Green = Meter in measurement mode and reading is below the set point. Orange/Yellow = Reading is above the set point and the relay is activated. Blinking Red = Indicates an alarm condition such as when the maximum dosing time has been exceeded. Fuse Protected Dosing Contacts The relay dosing contact is rated for up to a 2A load and is fuse protected. Labeled Termination Connections Quick-connect terminal blocks are clearly labeled for easy connection to power, conductivity probe and relay that can be used to operate a dosing pump, valve, audible alarm, or light.
