Installing the I/O Modules

The wiring for the different I/O module terminal blocks may vary. You should
read the user's manual for an individual module before wiring and installing
the module. Insert the I/O modules into the base, starting with the slot adjacent
to the PLC as shown in Figure 3-21.
Use supply wires suitable for at least 75_C. Signal wiring
connected in this box must be rated at least 300 V.
Employer des fils d'alimentation pour au moins 75_C. Le
cablage de signalisation raccorde dans cette boite doit
convenir pour une tension nominale d'au moins 300 V.

Figure 3-21 Location of I/O Modules in Base
The base power budget is determined from the power provided by the base
power supply and the requirements of the particular modules used. When
determining the I/O system layout, take care not to exceed the maximum power
available from the power supply.
The total power requirement for all modules drawing power from a Series 505
base must be less than or equal: 55 W at +5 VDC and 3.75 W at –5 VDC.
