Power limitations using multiple E-PDISO16 modules

The maximum output current of the supplied CB-PWR-9V3A power supply is 3 A. When running at full load

(all relays on and the Ethernet is active), the E-PDISO16 draws 1.7 A from the supply. If you daisy chain

additional Measurement Computing products to the E-PDISO16, make sure you provide adequate power to

each module that you connect.

A drop in voltage occurs with each module connected in a daisy chain system. The voltage drop between the

external power supply and the daisy chain output is 0.5 V max. Factor in this voltage drop when you configure a

daisy chain system to ensure that at least 6.0 VDC is provided to the last module in the chain.
