Module Installation Procedure (Power-Off)
Moxa’s ioPAC 8500 controllers come with 2, 5, or 9 slots for 85M-series modules. Use the following procedure
to install modules when your system is powered off.
Step1: Install the module into the ioPAC 8500 system. The module’s
PCB should align with the edge of the frame. Push the module into the
slot and make sure the module is plugged into the backplane.
Step2: Fasten the two screws using 3.5±0.5 kg of torque.
Module Installation Procedure (Power-On)
All ioPAC 8500 modules are hot-swappable, which means that you can safely install, remove, and replace
modules while the system is powered on. When a module is removed or installed when the system is powered
on, the module head stops processing and registers the newly installed or recently removed module, and scans
for a configuration change. There is no disruption to normal operation during module insertion or removal.
After installing a new module, it could take about ten seconds for the system to recognize and activate the
module, at which point the module’s LED will turn green.
WARNING
When the system is powered on, do not install more than one module at a time. If you need to install multiple
modules, wait until the most recently installed module’s LED turns GREEN before installing the next module.
Configuring Power
Powering on the ioPAC Controller
The ioPAC controller can receive power from a 9 to 48 VDC power source, and is compliant
with EN 50155 at 24 VDC. Input power is applied to the positive (V+) and negative (V-)
terminals on the connector.
•
When the input voltage is below the minimum recommended voltage the ioPAC will turn
off.
•
The ioPAC has reverse protection and power input over-voltage protection, allowing it to
resist a maximum voltage of 60 V, and the ioPAC’s power input over-current fuse
protection specification is 5 A.
After connecting the Moxa ioPAC controller to the power supply, it will take 30 to 60 seconds for the operating
system to boot up. The green Ready LED will illuminate continuously until the operating system is ready.
