-------2-Wire Operation- An external power supply delivering 10 - 35 VDC with minimum
current capability of 40 mA DC (per transmitter) must be used to power the control loop.
See Fig. C for connection of the power supply, transmitter, and receiver. The range of the
appropriate receiver load resistance (RL) for the DC power supply voltage available is
expressed by the formula and graph in Fig. D.
