Adjustable Dosing Relay
The BL932700 features a dosing relay which may be configured to dose above or below a user programmable mV setpoint.
Selectable Overdose Protection
The mini controller may be programmed to deactivate a valve, pump, or connected device if its activation continues over a selected time; adjustable from 5 to 30 minutes.
Selectable Control Override
With the flick of a switch, normal “Auto” operation may be overridden turning your connected device “Off” from operation or always “On.”
Analog Output Communication
The BL932700 features a 4 - 20 mA analog output for connection to a data logger, chart recorder, or other device.
External Disabling Feature
A normally open contact may connect to a level controller or flow monitor. This safety feature may be used to prevent continuous dosing in the event of specific or undesired system conditions.
Matching Pin Connection
An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
