Power Supply Requirements
An external 24V dc power supply is required to power the block. Total
current required to power the block is equal to 200mA plus an inrush of
5.5A for 10
µ
sec for each block. The supply must be able to source an
additional 100mA plus an inrush current of 400mA when a peripheral is
connected.
In addition, the external power supply should have current limiting
capabilities. The voltage range must not exceed 20.5–27.6V dc.
