Power Supply

Power Supply

Depending on the variant, the processor modules can be connected to the following supply voltages:

24 VDC	100 - 240 VAC

The electrical connection is established via a removable 5-pin terminal block. As the terminal block is also available as a spare part (inside TA570 Spare Part Set for AC500-eCo processor modules), further information on the terminal block for power supply and the terminal block for serial RS-485 adaptor is provided under TA570 - Spare Part Set.

The 24 VDC variant contains 2 L+ and M terminals. The L+ terminal on the left side is the input and the right side is the output. The M terminals are internally interconnected. The supply can be easily looped through to the onboard digital inputs.

Caution

:strong:Risk of damaging the processor module and the connected \ modules!

Voltages > 35 VDC (DC variants only) or > 288 VAC (AC variants only) might damage the processor module and the connected modules.

Make sure that the supply voltage never exceeds 35 VDC / 288 VAC.

Caution

:strong:Risk of damaging the processor module!

Excess currents at 24 VDC output (24 VDC processor module variant) will damage the processor module.

Use an appropriate fuse PM55x-xP and PM56x-xPwithin 24 VDC input connection.

The 100-240 VAC variant contains an internal power supply with a wide-range input. It provides a 24 VDC output at the terminals L+ and M which can be used to supply the onboard digital inputs.

Note

The voltage output at 100-240 VAC variants can provide 180 mA max. The output is protected against overload by a self-resetting fuse (PTC).

Note

According to IEC 60204-1:2016, where control circuits are supplied from an AC source, transformers having separate windings shall be used to separate the power supply from the control supply.
