ATI Technologies d12 series - Current Loop Receiver, Single Supply (3-Wire Mode); Figure 13. Current Loop Single Supply (3-Wire Mode)

ATI Series D12 Toxic Gas Transmitter with H10 Smart Sensor
Revision N (7/15) 18
Current Loop Receiver, Single Supply (3-Wire Mode)
The transmitter will source current to a loop receiver as shown. A single power supply provides both
primary and loop power to the transmitter. Size each power supply according to the number of
transmitters, the current demand of each (see specifications), and the wire resistance. The wire
resistance must not be allowed to drop the Primary Supply Voltage below 12V at the terminals of any
transmitter. Hint: if possible, use 12-14 AWG wire on supply connections (shown in bold).
