– Can be connected to 1 dosing pump.
– Manual calibration at any point from 0 comes 1999mg/L.
– HAVE 4-20mA analog output
– Connects to 1 HI7634 electrode with 2m, 4m or 5m long cable (buy separately).
+ BL983319-0: 12VDC adapter
+ BL983319-1: 115/230VAC
+ BL983319-2: 115/230VAC, analog output 4-20 mA
Fixed dose distribution relay
BL983319 has a default dosing setting relay which is a contact that closes when below the set point programmed by the user.
Overdose protection
The small controller can be programmed to shut off a valve, pump, or connected device when activated continuously beyond a selected time; Adjust from 5 to 30 minutes.
Switch control mode
With just one switch, normal “Auto” operation can be converted into “ON/OFF” mode.
Protective dosing
The mini controller is protected against a maximum of 2A load from one pump or connected device.
Connect peripheral devices easily
Quick and easy terminal connection to power, communications, dose control, or sensors.
