Unit Configuration Example
■
Minimal Configuration
Small Systems with 2 Channels or 4 Channels Communicating with the Host
Device via RS-485 (CompoWay/F Protocol)
•
Alarms can be allocated to the auxiliary output for the End Unit.
•
G3ZA outputs can be used.
■
Multiple Units without an EJ1N-HFU
Building Systems Communicating with the Host Device, such as a PLC, PT, or
Computer, via RS-485 (CompoWay/F Protocol)
•
The 2 auxiliary alarm outputs (transistor outputs) provided on the End Unit can be used for integrated alarm systems.
•
G3ZA outputs can be used.
•
Distributed placement is possible by using multiple EJ1C-EDU End Units.
