E3M080 Line module ”Collective”
9.1 Overview
Line module for
collective detectors
(digital comparator)
I-Bus module with common line processor for all
8 lines
2 line types available (programmable via SWE700A)
Line termination depending on programmable line type
Short circuit can be evaluated as fault or alarm per module (Programming switch
‘S4’)
Line inputs protected against over voltage
Card format 100mm x 200mm
I-Bus address is set at programming switch ’S3’
E3M080
Terminal block X20 (20 terminals)
- mounted on module chassis
- for the connection of the prefabricated cable to
connection level, or
- for direct connection of the periphery
Card chassis
- mounted on module chassis
