QUESTIONS & ANSWERS
Ask a Question-
I am looking to replace a E3SM part #1309A0047, your description refers to a E3SB w/the same part number and states they are identical, odd because every model usually has its own part number, but that is not how the description reads. Which part number/model do you have in stock?
E3SM is identical to 1309A0047 & E3SM is the direct replacement for E3SB (DOES MODBUS AND BACKNET).
