Intrinsic Safety Barriers Suitable For Use With Delta Controls Model 872

Delta Controls pressure transmitters are intrinsically safe when used with suitable safety barriers. Barriers are suitable if the entity parameters are selected so that:

13v < Vmax < 35v     20mA < Imax < 200mA         Ca > .05uF+Ccable        La > Lcable+220uH

In addition, the internal resistance must be selected so that at 20mA, the voltage dropped across the load resistance plus the internal resistance must be less than (Vsupply-13v)

The following are some of the safety barriers that are suitable for use with Delta Controls Model 872
