<h3 class="first"><span class="Apple-style-span" style="font-weight: normal; font-size: medium; ">hi wrenches,</span></h3><div class="content">I am installing some load controls for
a client who has a FM80 controller. I don't have experience with this
product. It has a 12V aux output that I wish to drive an SSR but the
wiring is complicated by the fact that this SSR also needs a power
supply as well as a control signal. I want to use 24V nominal system
battery for the SSR power and AUX for the signal. Can I connect the
grounds together?<br><br>Additional info. I am using a phase control
SSR driven by a 0-10 volt signal to control an AC load with phase angle
shift control. I plan to put an RC filter that converts the PWM output
of the AUX from the CC to give an analog voltage output that determines
the loading of the inverter. Crydom MCPC2450<br><br>thanks for any help before I go on site next week<br>Hugh</div></div></body></html>
