The voltages of the transmitters connected to Hollyland’s DCS are different

Thread Content

Our company’s DCS is from Allen-Bradley; why do some of the transmitters show a voltage of 23V while others have only around 20V? Please explain the reason
Reply #22009-08-06
No way, they’re all DC24V, 4~20mA standard signals, right?
Reply #32009-08-11
Where is the voltage measured? There is sometimes a voltage drop when measuring with the transmitter
Reply #42009-08-11
If there is a voltage drop, measure the voltage at the 24V output terminal; if anything is abnormal, check the grounding
