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 IF8U 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 IF8U module has the
following power requirements.
5 VDC 24 VDC
175 mA 21 mA
