ATI Series D12 Toxic Gas Transmitter with H10 Smart Sensor
Revision N (7/15) 16
Power Only, No Output Options
If there are no output options, transmitters may be powered from a single, primary supply as shown.
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 primary supply terminals of any transmitter. Hint: If possible, use 12-
14 AWG wire on primary supply connections (shown in bold), keep the number of transmitters low,
and verify the voltage on the on the transmitter furthest from the supply.
