Quick Review
• Standardized Dimensions and Parts
The KOFLOC Multifunction Readout Unit MODEL CR-500 retains the standard 48 x 96 mm, which makes it easy to integrate this unit into existing control panel.
•Flexible Power Supply
The power requirement of the KOFLOC Multifunction Readout Unit MODEL CR-500 is between 85 to 264 VAC, which allows this unit to function in most locations, and also providing power to MFC/MFMs at ±15 VDC (300 mA max.).
• KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
• Simultaneous control of multiple units
The KOFLOC Multifunction Readout Unit MODEL CR-500 uses RS485 serial communication for superior flexibility in configuration when controlling multiple units through a host computer.
• 6-Digit Totalizer display and Upper/Lower Alarm
The totalizer displayed on 6-digit display unit and upper/lower flow limit alarm functions are standard features of the KOFLOC Multifunction Readout Unit MODEL CR-500 as well as flow measurement, set point control and other functions necessary in controlling mass flow controllers and meters.
• Analog/Digital
The KOFLOC Multifunction Readout Unit MODEL CR-500 allows remote control of both digital and analog signals.
