Hi,
I have never used any solid state relay or contactor.
A customer want us to replace regular 100-c AllenBradley contactors with solid state. I saw that Allen Bdraley have 156-C line that are solid state. Is there anything that I have to think of when using these? The contactor is controlling a motor. It will have 24VDC control.
There is both options with fan and without, is it a problem with solid state that they are getting warm? So I benefit to have one with fan? (and with that an alarm output)
I read in the specs that:
Number of motor starts (x:6, Tx:6 s, F:50%) at 40 ˚C(2) 30 30 30 30 30 30 30 30
(2) Overload current profile definition: x: multiple of AC53a rating, Tx: duration of current surge, F: duty cycle
I can't really understand this. What does 30 represent? Starts per minute?
Any help is appreciated
