AO-8 and AO-8-H I/O Modules

arrow1_rotationAnalog outputs arrow1_rotationEspecificaciones

The AO-8 I/O module is an analog output, 8-channel I/O module.

Aviso

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

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 I/O modules are designed to be used for voltage or current outputs.

The I/O bus in the terminal base provides the I/O 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 I/O module and the SmartStruxure server device.

Voltage outputs
