Dosing Relay: contact close when measure > set point
BL 983327 is a panel mounted mini controller with an output relay that has been designed for easy, affordable installation in tight spaces—ideal for simple yet effective process control.
This instrument is provided with automatic compensation for variations in temperature. The probe (not included) is easy to clean and requires very little maintenance. The calibration is performed at one point, through a trimmer.
All wiring and connections to external devices are done through the terminals
on the rear panel. The multicolor LED continuously indicates if the controller is in measurement, dosing or alarm mode.
Users can choose automatic or manual dosing mode by a switch on the front panel. Manual control is particularly useful during maintenance operations because it permits operators to enable or disable the dosing relay according to need. To help prevent overdosing, the overtime control system advises users when the relay is active
too long.
