D3--04AD 4-Channel Analog Input

Standard 4 to 20 mA transmitters and transducers can operate from a wide variety of

power supplies. Not all transmitters are alike and the manufacturers often specify a

minimum loop or load resistance that must be used with the transmitter.
The D3--04AD provides 250 ohm resistance for each channel. If your transmitter

requires a load resistance below 250 ohms, then you do not have to make any

adjustments. However, if your transmitter requires a load resistance higher than 250

ohms, then you need to add a resistor in series with the module.
Consider the following example for a transmitter being operated from a 36 VDC

supply with a recommended load resistance of 750 ohms. Since the module has a

250 ohm resistor, you need to add an additional resistor.
