1 Introduction 

 
 

1.1 General information

 

 
This manual contains necessary informations for product integration to ensure the functional safety of related loops. 
All the failure and the HFT of the module are specidied in the FMEA analysis 
 

 

 

 

Other documents ---Applicables

- Technical datasheet CAL4-100ig 

 

 

 

 

 

- UE conformity declaration CAL4-100ig 

 

 

 

 

 

- FMEA analysis AMDEC_CAL4-100ig

The assembly, installation, commissioning and maintenance can only be performed by trained personnel, qualified and have read and 
understood the instructions in this manual. 
 
When it is not possible to correct the defects, the equipment must be decommissioned, precaution must be taken to protect against 
accidental use. Only the manufacturer can bring the product to be repaired. 
 
Failure to follow advice given in this manual can cause a deterioration in security features, and damage to property, environment or 
people. 
 

1.2 Functions and intended uses 

 
The transducer CAL4-100ig provides isolation and duplication of analog current loop 4 ....20mA. 
an auxiliary power supply for a loop powered sensor is available. 
 
The devices are designed, manufactured and tested according to security rules. 
They should be used only for the purposes described and in compliance with environmental conditions 
contained in the data sheet:

1.3 Standards and Guidelines

 

 
The devices are evaluated according to the standards listed below: 
 
• Functional safety according to IEC 61508, 2000 edition: 
Standard for functional safety of electrical / electronic / programmable electronic relative to electronic safety. 
 
The evaluation of the material was performed by "

failure modes and effects analysis"

 

(IEC 60812 - Issue 2 - 2006) 
to determine the device safe failure fraction (SFF)  
 
The FMEA is based on (IEC 62380-2004) 
Reliability data handbook. Universal model for reliability prediction of electronics components, PCBs and equipment
