AO-8 and AO-8-H
Introduction
The AO-8 and AO-8-H are analog output, 8 channel I/O modules.
The analog outputs are capable of supporting analog voltage or current point types. Therefore, analog outputs support a wide range of devices, such as actuators.
Function
The modules are part of a modular system that delivers power and communications on a common bus. Connecting modules is a one-step process: just slide the modules together using the built-in connectors.
Each module can be separated from its terminal base to allow the site to be wired prior to the installation of the electronics. The patented locking mechanism serves as handles for removing the module from its base. All critical components have a protective cover that permits convection cooling to occur.
Because critical applications require 24-hour operation, Schneider Electric designed the I/O modules for hot-connection of terminal bases and hot-swapping of the modules to their bases. This design ensures continuous power and communication during service operations.
The auto-addressing feature helps eliminating the need for setting DIP switches or pressing commission buttons. Each module automatically knows its order in the chain and assigns itself accordingly – significantly reducing engineering and maintenance time.
Fasteners easily snap into a locked position for panel installation. The fastener has a quick-release feature for easy DIN-rail removal.
The I/O module terminals are clearly labeled and protected by transparent covers. The input and output terminals are at the top and bottom of each module and are accessible for maintenance without removing the module. The EcoStruxure Building Operation WorkStation software can generate custom as-built labels for each module. Pre-perforated letter and A4 size label sheets are available as an accessory.
The SmartX devices use built-in connectors for single row connectivity, side by side. If a panel size requires multiple rows, extension cords are available.
The I/O module has a status indicator that denotes the health and status of the module.
The front panel of the AO-8-H includes Hand/Off/Auto (HOA) switches to provide override control of the analog outputs.
Each output also has a potentiometer to modulate the output signal when the switch is in the Hand position.
The position of the HOA switch is readable through user interfaces, such as the EcoStruxure Building Operation WorkStation software, enabling more precise monitoring and control.
Protection components on the analog outputs protect against high-voltage short-duration transient events.
The analog outputs have current limits to protect against permanent short-circuit to ground.

For protection from excess current that could be produced by field wiring, follow these instructions:
Connect one RET terminal on each of the I/O modules to a common chassis/power ground rail in the control panel using a size 16 AWG, 1.3 mm 2 , or larger wire.
Individual 24 VDC power sources to the field must be current limited to maximum of 4 amps for UL compliant installations, and no more than 6 amps in other areas.
For more information on wiring, see Hardware Reference Guide.
