Install Your Micro800 Expansion I/O Chapter 4
To remove your module from the DIN rail, pry the DIN rail latch downwards
until it is in the unlatched position.
Panel Mounting
The preferred mounting method is to use two M4 (#8) per module. Hole spacing
tolerance: ±0.4 mm (0.016 in.).
Follow these steps to install your module using mounting screws.
1. Place the module next to the controller against the panel where you are
mounting it. Make sure the controller and module are spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet
then remove the module.
3. Drill the holes at the markings, then replace the module and mount it.
Leave the protective debris strip in place until you are finished wiring the
module and any other devices.
System Assembly The Micro850 expansion I/O module is attached to the controller or another
I/O module by means of interconnecting latches and hooks. The Micro850
controller and expansion I/O modules must terminate with a 2085-ECR Bus
Terminator module.
ATTENTION: Failure to connect a bus terminator module to the last
expansion I/O module will result in a controller fault.
