MODEL CR-400
The CR-400 readout unit, when connected to your mass flow control-ler or meter with a cable, provides the key mass flow functions, such as flow measurement and control as well as cumulative flow calcula-tions and flow event outputs. This readout unit offers RS-485 commu-nications capability, so multiple readout units can be controlled online by a host computer. * The CR-400 is fully compatible in size with the CR-300.
Features
- Total flow is displayed in 8 digits : The upper 4 digits and the lower 4 digits are shown alternately.
- Various event outputs are available.
- With a width of 73mm and height of 73mm, it takes up little space.
- Equipped with forced open/close operation of mass flow controller valve.
- External control terminals are provided on the rear for remote control
- Mass flow control by RS-485 communications
- A lock key prevents accidental operation.
- Mass flow power : ±15 VDC (300 mA)
- Mass flow power: ±15 VDC (300 mA)
