indicates a fuse.
• The power for the analog module should be supplied separately from the LT. Turn
the analog module on before turning the LT on. Wait at least 30 seconds after
power-off to restart the external power-supply or it may not operate properly.
• Use the braid supplied with the module to connect the functional ground.
• Connect an appropriate fuse for the applied voltage and current draw, at the position
shown in the diagram.
• To avoid disturbances on the analog outputs, the power supply of the EXM-AVO2HT
module must be turned on or off at the same time than the base controller power supply.
15.11 2-ch analog-input/1-ch analog-output module
The detail of the external power supply is: the rated supply voltage is 24 VDC, the rated
input voltage ranges from DC20.4 to 28.8 V The consumption current is 45 mA

(24VDC) when the input is not-open, output 100%. You can select either voltage or
current for each inpu or output channel.
