(b) Ideas for reducing voltage drops

The following methods are effective to reduce voltage drops at the extension cables.

1)Changing the module loading positions

Load large current consumption modules on the main base unit. Load small current consumption modules on the extension base unit.

2)Using short extension cables

The shorter the extension cable is, the smaller the resistance and voltage drops are.

Use the shortest possible extension cables.

(2)When the base unit is of Q3†SB:

Slim type power supply module Q61SP

Slim type main base unit Q32SB, Q33SB, Q35SB

CPU module 1 Q02(H)CPU, Q06HCPU, etc.

I/O module

QX10, QY10, etc.

Intelligent function module Q64AD, QJ71LP21-25, etc.

Peripheral devices, converter, cables, etc. (for connection between CPU module and PC)

1: The CPU module is loaded on the Q3SB slim type main base unit.

(a)To use the slim type main base unit and slim type power supply module, pay attention to the capacity of the 5VDC power supply.

1)The capacity of the 5VDC power supply of the power supply module (Q61SP) installed to the slim type main base unit is 2A. Choose modules with total capacity of 2A or less.
