AO-8 and AO-8-H Central IO Modules

arrow1_rotationAnalog outputs arrow1_rotationSpezifikationen

The AO-8 and AO-8-H Central IO modules are analog output, 8-channel I/O modules.

Hinweis

Module names with an -H indicate the presence of Hand-Off-Auto override switches.

Hinweis

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 shows the module status LED, override switches, and adjustable potentiometers.

Analog outputs

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.

Voltage outputs
