Power Considerations

Choose between two CLICK power supplies or supply your own 24 VDC power
No Power Budgeting required if you choose model C0-01AC
Power Budgeting calculator included in the FREE CLICK software (Download here)
Power Budgeting calculator is also included in our online Configuration Tool

	Choose:		Or:

C0-00AC		C0-01AC		User Supplied
0.5 A 24 VDC Output 100-240 AC Input		1.3 A 24 VDC Output 100-240 AC Input		We recommend our own Rhino brand 24VDC power supplies.

All CLICK CPUs and I/O Modules require 24 VDC power to operate (PLC Power). If you select the C0-00AC power supply (0.5A) or if you supply your own PLC Power, you should total up the PLC power required by the CPU and any modules you select (see column two of the chart) to verify that you will have enough 24 VDC to operate the PLC.

If you choose the C0-01AC power supply, you don't have to bother with power budgeting - it supplies enough current to power any CLICK CPU and any combination of up to 8 I/O modules (the maximum allowed).

Field Power

All inputs and outputs on a CLICK PLC are optically isolated from the internal power and signals in the PLC to help prevent noise issues. Some CLICK output types require a little Field Power to power the opto-couplers on the outputs. For maximum noise immunity, it is recommended that this power be supplied from the same source as is used to power the field devices. The amount of field power required is shown in the third column of the chart.

Power Budgeting Using the CLICK Programming Software
The following example shows the current consumption as calculated in the CLICK Programming software. The System Configuration screen displays the current required for each component, and calculates the total power required as you select and add modules to a CLICK system. If you select a CLICK power supply, and you exceed its capabilities, the power budget row is highlighted in red.
