Concept
AO-V-8 and AO-V-8-H I/O Modules
The AO-V-8 I/O module is an analog output, 8-channel I/O module.
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.
AO-V-8-H I/O Module
Analog outputs
The analog outputs of the AO-V-8 and AO-V-8-H I/O modules are designed to be used for voltage outputs.
Voltage output internal configuration and connection of external resistive load
R OUT is approximately equal to 10 ohm.
V OUT range is 0 to 10 VDC.
R LOAD minimum is 5 kohm.
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.
