NOTE: Switching Pilot Duty Devices Such As Control Coils For Relays Or Contactors Produces An Electro-Magnetic Force When De-Energizing Those Type Of Loads. To Protect The Controller's Electronic Circuitry From The Inductive User Load, The Use Of An RC Suppressor Also Known As A Snubber Device Should Be Wired Between The Load And The Load Output Terminal Of The Controller. An Exception Is The Use Of Watlow Solid State Relays Having Internal RC Suppression.

Two Wire Bus Communication Interface Type EIA-485 Also Known As RS-485 Comes Standard With All PM Series Controllers Which Can Provide An Easy Alternative to Setting Up Program Menu Options. Various Profiles Can Be Configured And Saved As Files And Can Be Up Loaded To Other PM Controllers. USB To Serial Converter Is Required To Connect The PM Controller To Any Computer With A USB Port.
