Questions
About this item
Is the base included?
No. The box holds the head and a dust cap; order the LP720 base separately. The housing is IP40, or IP42 with an RS720 seal.
What happens if the loop shorts?
An EN 54-17 isolator sits inside, so neighbouring addresses stay on the loop. Quiescent current is about 220 µA.
