Adjustable Dosing Relay
The BL982411 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.”
Fuse Protected Dosing Contacts
The mini controller is protected for up to a 2A load from a connected pump or device.
Easy Peripheral Connection
Quick-connect terminal blocks provide for easy connection to power, communication, dosing control, or sensors.
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.
