BL 983317 and BL 983327 are panel mounted mini controllers with an output relay, that has been designed for easy, affordable installation in tight spaces, ideal for simple yet effective process control.
They are provided with automatic compensation for variations in temperature. The probe is easy-to-clean and requires very little maintenance. The calibration is performed at 1 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.
You can also choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits you to enable or disable the dosing relay according to your need. The overtime control system advises you when the relay is active too long, helping to prevent overdosing.
Models are available with power supply input at 115/230 Vac or 12 VDC
