This optional module combines the EtherNet/IP and
Remote Amplitude Control interfaces. See Pages 31-32
for information on the EtherNet/IP connector.
This module enables remote control of output amplitude of
the iQ system. The control interface is a 4–20mA current
loop. The current loop connector and fault indicator are
shown below in Figure 11–10. The output can be adjusted
from 36% to 100%. The scale factor is a 4% amplitude
change for each mA change. A graph of amplitude output
as a function of loop current is shown in Figure 11-9. The
current loop compliance voltage is 6 volts minimum.
Failure to provide at least 4mA of loop current is sensed as a
fault and will produce minimum amplitude output.
The current loop fault indicator is a bi–color LED. It is green
when the current is between 4 and 20mA and red when the
current is below 2mA.
Current Loop Fault
If a current loop source is not available, an external +24VDC
power supply can be connected to the POS and NEG terminals
of J7. (See Figure 11-11.) A +22VDC supply is also available
on System Output Pins 1(+) and 3(-).
