IFM24160, internal power-supply module
The IFM24160 internal module supplies and distributes power through the CAN drive connection bar and through the
two outputs, OUT 1 and OUT 2.
In installations where several control panels are connected in a network, it is necessary to use an IFM24160 power-supply
module for each control panel.
In installations where the control panel comprises more than one cabinet, you can install a power supply in each cabinet.
The total voltage available equals the sum of the voltages of each power supply added together minus 1A for correct
cable balance.
FPMCPU comes with:
• battery connection wire with thermal probe
• battery to battery connection wire
• 3 screws for securing the module to the grounding bar
• wire with eyelet terminal for connection to earth
• 1 ferrite
• Instructions manual
