Features BL-983324-0 TDS Mini Controller (Range up to 49.9 ppm ) :
- The meter is provided with a dosing relay, activated when the TDS reading exceeds the set point value.
- Measurements are automatically compensated for temperature variations and shown on the large display.
- A multi-coloured LED on the front panel continuously indicates if the mini controller is in measurement, dosing or alarm mode.
- Wiring and external device connections are extremely simple to perform through the terminals on the rear of the instrument.
- Choose an automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations as it allows the dosing relay to be enabled or disabled according to requirements.
- The overtime control system advises you when the relay is active too long, helping to prevent over dosage.
- Model is available with power supply input at 230 Vac – 12 Vdc.
Order Information:

Adjustable Dry Contact Dosing Relay
The BL-983324-0 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.
Multicolour LED Indicator
Multicolour 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.
Labelled Termination Connections
Quick-connect terminal blocks are clearly labelled for easy connection to power, conductivity probe and relay that can be used to operate a dosing pump, valve, audible alarm, or light.
