Can I connect several ITP11 displays to the common analog output? How should I connect them, in series or in parallel?

The number of the connected displays depends on the available supply voltage because each ITP11 causes a voltage drop of about 4 V. For example, an external voltage source of 24 V connected to a 4-20mA analog output of a Programmable Relay PR200 supports up to 5 ITP11 displays (without any other loads).

The connection should be performed in a series circuit.
