Product Details

A power supply module is selected based on to the total current consumption of I/O modules, special function modules and peripheral devices to which power is supplied by the power supply module. When an extension base unit, A52B, A55B, or A58B is used, take into consideration that power to the module is supplied by the power supply module on the main base.

For 5VDC current consumption of I/O modules, special function modules and peripheral devices, refer to Section 2.3. For devices purchased by users, refer to the manual for each device.

Selecting a power supply module when using extension base unit(s), A52B, A55B, and/or A58B

When an extension base unit, A52B, A55B, or A58B is used, 5VDC power supply is supplied from the power supply module on the main base unit via an extension cable.

When mounting a power supply module on the main base unit, select a model that can cover 5VDC current consumed by modules mounted on the A52B, A55B, and/or A58B.

Since power to the A52B, A55B, or A58B is supplied via an extension cable, a voltage drop occurs through the cable.It is necessary to select a power supply module and cables with proper length so that 4.75VDC or more is available on the receiving end.

For details of voltage drop, refer to Section 6.1.3 Application Standards of Extension Base Units.

Handling precautions for the A66P: Use the A66P on the base unit where no module, a dummy module or a blank cover is installed to the rightmost slot or the right adjacent slot. The A66P output current (24VDC) depends on the left-hand adjacent module as shown below.
