RTD to 4-20mA Converter-SIL3
Does anyone has idea about SIL3 certified Isolator/Barrier for
Input : 3/4 Wire RTD
Output : 4-20 mA.
AFAIK most major manufacturers have Analog Signal conditioner/Isolator products certified upto SIL2. One manufacturer whose products we regularly use is G# Inter********, which has SIL3 certified isolators for discrete signal isolation and SIL2 certified isolators for analog signal isolation.
A quick internet search of well known manufacturers, leads to products which are certified only upto SIL2 for analog temperature signal isolators.
An enquiry to a product manufacturer's sales team would be more fruitful.
