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. For more information, see 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.
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.
