Description: Input: single ended Output: 0/4.20mA BLOCK DIAGRAM FEATURES. The same module can also provide operating power to the field transmitter if it is a two-wire device. Further, by using 4-20mA as the driver, the voltage produced across a load resistor is easily scaled by simply changing the resistance. Industry standard approach is to use a signal converter to accept the 4- 20 mA input, provide isolation and noise immunity (EMI & RFI), and present a 0-10 Vdc signal to the board. If from the DA board, this is another source of a ground loop. It can provide 24V isolated distribution power to the transmitter in input and convert the transmitters output signal into standard dc current voltage signal.
Terminology to keep in mind includes: 1 mA = 0.001 AMP (short for amperes) Amps are referred to as CURRENT How to convert 4 20 ma to 2 10v? HIC IAG Isolated 4-20mA to 0-5V 0-10V current voltage signal converter is a high accuracy reliable din rail-mounted analog current voltage signal isolated conversion and amplification module. When do you convert ma to voltage in hvac?Ĭonverting mA to voltage is common in HVAC when working with pressure transducers. Common secondary meters or acquisition cards generally accept input signals of one or more of the above formats. Very easy to use, it can be connected with micro USB-5V power supply or DC 15-30V external power.
Common transmitters or sensors use one or more of the above formats to output standard signals. UCTRONICS signal generator is designed to simulate 0-10V voltage signal and 0/4-20mA current signal for PLC and panel Debugging, Device Testing, Frequency Converter, Flow Valve, ect. The 4-20 ma signal transmitter acts as a constant current source with fairly high compliance. 4-20mA Current loop output is a type of electrical signal that is used in a series circuit to provide a robust measurement signal. Common standard analog signals are: 0-5V, 0-10V, 5V, 10V, 4-20mA, 0-20mA or 4-24mA. The critical specification for the Op-Amp would be common mode input voltage range. You could actually use a 312.5 ohm resistor and an instrumentation Op-Amp toground reference the signal to 0-5 volts. This assumes that you have sufficient resolution in your A/D conversion (minimum of 12 bit - 4095 counts) to meet the accuracy needs of your system. If overrange is possible, you might consider converting the signal to 1-5 VDC using a 250 ohm resistor and setting the appropriate range in the logic.
