EJA-E series transmitters except Fieldbus,  PROFIBUS PA and 1-5V DC with HART (Low Power)  communication types are certified in compliance with  the following standards; IEC 61508: 2000; Part1 to Part 7 Functional Safety of Electrical/electronic/ programmable electronic related systems; SIL 2  capability for single transmitter use, SIL 3 capability  for dual transmitter use.

FUNCTIONAL SPECIFICATIONS

Output “◊” 

For 4 to 20 mA HART / BRAIN (Output signal code D and J) 

Two wire 4 to 20 mA DC output with digital  communications. 

BRAIN or HART FSK protocol are superimposed on  the 4 to 20 mA signal. 

Output range: 3.6 mA to 21.6 mA 

Output limits conform to NAMUR NE43 can be preset  by option code C2 or C3. 

For 1 to 5 V HART (Output signal code Q) 

Three or four wire low power 1 to 5 V DC output with  HART, linear or square root programmable. HART  protocol are superimposed on the 1 to 5 V DC signal. Output range: 0.9 V to 5.4 V DC
