Connecting to external devices
-
Hi there, I have to dig into the pleasent toppic of establishing connection between computer and some external device of the industrial automation area. Problem: an adapter from 4-20mA to RS232 would be needed. Do you know where to get them (or at least where to get info on them)? Thanks for your kind help.

RaGe, thankx for your reply. Example: a remote pressure sensor, which has an output current signal 4-20 mA (4mA refers to 0 pressure, 20 mA refers to maximum pressure, 10 barg). I have have to display the pressure as a function of time. 4-20mA is a 2-wire cable which I cannot connect to the serial port, as a result of which I will need an adapter which would convert a 2-wire current output of pressure sensor to an understandable signal for the serial port. I am interested in any kind of equipment which can directly be connected to the computer over serial port. Thankx Bunburry
