Hi,
I’m using an AB7007/AB7072 to connect to Hamilton probes;
pH, Dissolved Oxygen and Viable Cell Density.
They require 24V supply but the Serial port of the AB7007/AB7072 produces only 5V.
I know it is possible to supply the probes with 24V independently but my questions are as follows;
-
If I have nothing drawing current across pins 1 (5VOUT) and 5 (Ground) of the Serial port, will this generate an error/red LED/prevent Ethernet/Modbus comms?
-
If an alarm is generated, can it be handled with some implementing some kind of resistive arrangement, to convince the Anybus it is connected properly?
Thanks in advance of a reply!
Kind Regards,
Christopher
