Compact size Indicating Totalizer with CE marking and complying with RoHS


IR1600 is an indicating totalizer. Connecting with flowmeters having pulse outputs, it indicates alternatively instantaneous or totalizing flow output. Scaling, alarms and other parameters can be set through a key operation on front panel. Supplying built-in power of 12V DC for sensor, it receives 3-wire pulse signals. IR1600 compact housing of DIN48 x 24 is just the right size for your space saving control panel.
