We purchased a (PR52-9) 4-20mA current receiver. We intend to use these units with various types of 4-20mA loop powered devices.
Currently we use various brands of current/voltage receivers (Data Logger, PLC or I/O module) that for the most part require an external 24V power supply and a resistor within the circuit sized to match the voltage requirements of the receiver. As an example an I/O module with a 0-5V analog input channel.
- Will we need a separate 24V power supply and a resistor with this unit?
- Some of our existing units have a ADC converter on-board so the output is a value from 0 - 1023. What is the output of this device? A value representing actual current or voltage or is it a converted value from 0 -1023.
- One of the ultrasonic sensors we use has a output signal of 0 -1 volts. What is the recommended hardware solution for a device of this type?
- Would a Current Loop Input endNode be a better choice for our needs?
Thank you for your help.
