Contrec 114D DC Powered Batch Controller
The Model 114D Batch Controller is designed for flow applications where the precise control of batch quantities is required. Batch Total, Accumulated Total and Preset values can all be displayed on the large LCD display. The 114D has an input conditioning circuit which will accept pulse or frequency flow signals generated by turbine, positive displacement, paddlewheel or other flowmeters.
The 114D will operate from an external power source between 9 and 28 Volts and draws no more than 4mA. Lithium batteries provide backup if the DC power is interrupted so that totals are not lost. The solenoids or sensors, however, may still require external power. Solid state outputs provide control to solenoids and relays, and can sink up to 200mA.
