You can put any number of analog display/receivers in series from a single transmitter subject to two limitations:
1) The total resistance of all devices in the loop cannot exceed the maximum allowable load for the transmitter. PAy particluar attention to loop powered devices, as they "look like" very high impedence loads at low transmitter signals.
2) Only one device in the loop may be tied to power supply common or ground. For example, chart recorders often have internal connections between power supply "-" and the signal "-". PLC inputs often have the same arrangement. If two devices tie the signal to common "-" only the first in the series will get the 4-20 mA signal. In that case you need to add signal isolators.
