DO-FC-8 and DO-FC-8-H Central IO Modules
The DO-FC-8 and DO-FC-8-H Central IO modules are digital output, Form C relay, 8-channel I/O modules.
Module names with an -H indicate the presence of Hand-Off-Auto override switches.
The override switches on Central IO modules with manufacturing date earlier than 2021-W26 must be disabled to remove the risk of an improper output. Für weitere Informationen siehe Important Information on Central IO Modules with Manufacturing Date Earlier Than 2021-W26 .
The front panel includes dedicated two-color (red and green) status LEDs for local monitoring of digital outputs. You can configure these LEDs to display either red or green for each output state.
Digital outputs
The Form C digital outputs of the DO-FC-8 and DO-FC-8-H Central IO modules are switching contacts with one common terminal (C), one normally open terminal (NO), and one normally closed terminal (NC). The terminals are isolated from signal ground.
The I/O bus in the terminal base provides the Central IO module with power and an address.
The address value in the I/O bus is increased by one for each terminal base. The I/O bus also enables RS-485 communication between the Central IO module and the automation server.
