DO-FA-12 and DO-FA-12-H Central IO Modules
The DO-FA-12 and DO-FA-12-H Central IO modules are 12-channel, Form A relay, digital output 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. Para mais informações, consulte Important Information on Central IO Modules with Manufacturing Date Earlier Than 2021-W26 .
The front panel includes a dedicated two-color status LED that provides local monitoring of the digital outputs. You can configure the LED to display either red or green for each output state.
Digital outputs
The Form A digital outputs of the DO-FA-12 and DO-FA-12-H Central IO modules are normally open contacts with one common terminal (C) and one normally open terminal (NO). 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.
