For environments with extreme vibration and shock
concerns, use the panel mounting method described
below, instead of DIN rail mounting.
PanelMounting
Use the dimensional template shown below to mount the module. The preferred
mounting method is to use two M4 or #8 panhead screws per module. M3.5 or #6
panhead screws may also be used, but a washer may be needed to ensure a good
mechanical contact. Mounting screws are required on every module.
PowerRequirements
The maximum number of OF8 modules that can be installed in a system depends
on the maximum bus current draw of the module and the maximum bus current
provided by the PLC. The OF8 module has the following power requirements.
5 VDC 24 VDC
30 mA 250 mA @ 18.7 V, 195 mA @ 24
V
Use the table below to determine the maximum number of OF8 modules that can
be installed in a MicroLogix system.
