Remote Amplitude Control
Module
Part Number - 110- 4183
This optional 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 10–12. 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 10-11. 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 10-12.) A +22VDC supply is
also available on System Output Pins 1(+) and 3(-).

Future Availability
In the future, Remote Power Regulation Control will
become available. This option module will be able to
remotely control the power regulation setpoint using new
user-selection menu choices made from the front panel.
