RMS
Current Calculator
When starting and stopping motors frequently, the RMS current (which causes heating) will
be higher than the normal running current. This calculator will calculate the RMS current
to allow you to select the proper solid state relay heatsink.

Bleeder
Resistor Calculator
Solid state outputs (SCR's, triacs) from sensors and PLC outputs will supply a small
leakage current when they are in the off state. This current may cause problems with the
device they are switching (relays, PLC inputs) - they may appear to always be on. To solve
this problem, a resistor is placed across the input. This calculator will determine the
value of the resistor.
