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.
