Testing methods of reducing relay contact damage
Load - 3/4 ntp 60W 120vac 120psi H valve

1) 4.7K resistor, 1.3W of heat dissipation. Extra 16.5mA of current. 5% impedance 
2) RC suppressor that came with the valve. 1.4mW of heat dissipation. Extra 11.9mA 2.5% impedance 
3) Zener suppressor recommended from the plc manufacturer

Wandering what effect each actually has on the valve. 
Timing is not important as reactions must be less than 1500ms
