The AO-8 and AO-8-H Central IO modules are analog output, 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. Para obtener más información, consulte Important Information on Central IO Modules with Manufacturing Date Earlier Than 2021-W26 .
The front panel shows the module status LED, override switches, and adjustable potentiometers.
The analog outputs of the AO-8 and AO-8-H Central IO modules are designed to be used for voltage or current outputs.
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.
R OUT is approximately equal to 10 ohm.
V OUT range is 0 to 10 VDC.
R LOAD minimum is 5 kohm.
I OUT range is 0 to 20 mA.
R LOAD maximum is 650 ohm.
