Sourcing IS Barrier for Ultrasonic Transmitter
Sourcing IS Barrier for Ultrasonic Transmitter
(OP)
Can anyone assist in sourcing an IS Barrier for Ultrasonic Transmitter for a 4-20mA loop powered signal?
I've contacted MTL already who state that a suitable barrier cannot be found based on the figures quoted in the instrument operation manual as follows:
Ui = 23V
Ii = 40mA
Pi = 70mW
Typical values for MTL and Pepperl and Fuchs 4-20mA barriers are:
Uo = 28V
Io = 93mA
Po = 0.65W
The control cubicle housing the barriers is under manufacturing now, so I would really appreciate a response

In other words, you should contact Siemens for details on the necessary IS barrier.
