Power Transformer Selection
Select a 24 VAC transformer based on the maximum power requirements indicated on the transmitter label (20 VA) or
from the table below. The operating supply voltage (transmitter power “ON” with all sensor probes connected) should
not be less than 22.8 VAC or greater than 26.4 VAC.
Connecting Power to the Transmitter
Slide the cover plate up and off of the transmitter enclosure, and ensure that the power switch is in the “OFF” position
before connecting the 24 VAC power source.
Connect 24 VAC power to the large, two position power input terminal labeled “POWER” on the upper right hand side of
the main circuit board (Figure 5). Since the output signals are isolated from the power supply, it is not necessary to pro-
vide an isolated (secondary not grounded) power source.
Multiple GTx116 transmitters wired to a single transformer must be wired “in-phase” (L1 to L1, L2 to L2).
