20 E3M071 Line module ”Interactive” (supersedes E3M070)
20.1 Overview
z Line module for interactive detectors
z I-Bus module with line processor and independent emergency operation proces-
sor
z Designed for 1 loop line or stub line
z With 24 V supply output
z Line inputs and supply outputs protected against over voltage
z integrated ground fault monitoring (not contained in E3M070)
z Line is galvanically isolated from the control unit (not contained in E3M070)
z Card format 100 mm x 200 mm
z I–Bus address is set at programming switch ”S3”
