BL-981411-0
The BL-981411 is a compact, pH process controller designed for applications where space or cost is important. The device contains a high impedance pH input and may be used with any pH electrode with a standard BNC connector.
Mini panel-mount pH controller 12 volt supplied with wall brackets & 12vdc adapter.
**Please ask for HI-75220VAC when planning to use in Europe, and ask that HI-12VDC be removed.**
Adjustable Dosing Relay
The BL981411 features a dosing relay which may be configured to dose above or below a user programmable pH 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.
Mains powered - All mains operated equipment is compatible with UK AC voltage and frequency – 230V, 50Hz.
Interchangeable Electrode - One controller for all jobs thanks to HANNA’s wide range of interchangeable electrodes. Simply change the electrode for the task ahead.
