ADCA BLOWDOWN CONTROLLER BCS220 DESCRIPTION The ADCATrol BCS220 is a blowdown controller specially designed for use with steam boilers. The device takes care of both TDS and intermittent blowdown controls. TDS (Total Dissolved Solids) is controlled through measurement of the boiler water electrical conductivity and intermittent control is performed via a blowdown timer. The device utilizes a clear multifunction LCD to display measured conductivity, temperature, operational alarm status and provide an intuitive user interface. The device is IP 66 rated NEMA 4X and can be panel, surface/wall and pipe mounted. MAIN FEATURES TDS and intermittent blowdown control in one single device. Displays conductivity, resistivity, PPM and temperature units. Programmable cell constant. Versatile IP 66 NEMA 4X (144 x 144 mm) enclosure design. Large informative 3,75’’ LCD backlit display. Simple intuitive menu structure with soft tactile function buttons. Software upgradable via SD card slot – Future proof. Volt-free outputs with multiple alarm function options. 0(4) to 20 mA analog output for remote monitoring purposes with features including adjustable scaling, selectable on-error states and loop fault detection. Digital input suitable for connection to the boiler stand-by/burner contact, to reduce energy waste. OPTIONS AND ACCESSORIES: Panel mounting kit. Pipe mounting kit (50 to 100 mm pipe OD). AVAILABLE MODELS: BCS220 – 90 to 265 V AC power supply. BCS220-LV – 12 to 30 V DC power supply. VALSTEAM ADCA We reserve the right to change the design and material of this product without notice.
