BL 983318 is a mini controller that has been designed for easy, affordable installation in tight spaces, ideal for simple yet effective process control.
BL 983318 features ATC (Automatic Temperature Compensation) and simple one point calibration performed through the trimmer.
The multicolored LED continuously indicates if the controller is in measurement, dosing or alarm mode.
Wiring and external device connections are extremely simple to perform through the terminals on the rear of the instrument.
Users can choose automatic or manual dosing mode with 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.
The overtime control system advises users when the relay is active too long, helping to prevent over-dosage.
BL 983318-0 (12 VDC) and BL 983318-1 ( 115/230V) are supplied with mounting brackets, transparent cover and instruction manual.
