Illustration 3.23: Principle diagram for Analog I/O mounted in frequency converter.
Analog I/O configuration
3 x Analog Inputs, capable of handling following:
• 0 - 10 VDC
OR
• 0-20 mA (voltage input 0-10V) by mounting a 510Ω resistor across terminals (see NB!)
• 4-20 mA (voltage input 2-10V) by mounting a 510Ω resistor across terminals (see NB)
• Ni1000 temperature sensor of 1000 Ω at 0° C. Specifications according to DIN43760
• Pt1000 temperature sensor of 1000 Ω at 0° C. Specifications according to IEC 60751
3 x Analog Outputs supplying 0-10 VDC.
NB!
Please note the values available within the different standard groups of resistors:
E12: Closest standard value is 470Ω, creating an input of 449.9Ω and 8.997V.
E24: Closest standard value is 510Ω, creating an input of 486.4Ω and 9.728V.
E48: Closest standard value is 511Ω, creating an input of 487.3Ω and 9.746V.
E96: Closest standard value is 523Ω, creating an input of 498.2Ω and 9.964V.
