NÅNO Flow Computer
Hardware Overview
Field I/O
- Every field I/O point individually Galvanically Isolated
- The field RS485 communications port is opto-isolated
- Six individually isolated high accuracy Analog Inputs selectable for 4-20mA or 1-5V mode
- Two Analog Inputs can be set to 4-wire RTD mode
- Two individually isolated Analog Outputs (high resolution DACs)
- Four individually isolated Meter Pulse Inputs, can be used individually, for dual-pulse or as densitometer inputs
- Nine individually isolated Digital Inputs with fleeting detection
- Eight individually isolated Digital Outputs
- Two of the Digital Outputs can be used as Pulse Outputs or PWM outputs
General
- Four Serial ports
- Two Ethernet ports supporting 10/100MHz half & full duplex
- Wide range DC input voltage, 5 watt maximum
- High vibration tolerance due to robust mechanical design
- Optional integral display
