Power Supply and Connection
The Stamp PLC was designed to be powered by a 24 VDC supply. If you are simply running the Stamp
PLC on the bench-top, you can use any 24VDC @ >=300mA supply. Parallax offers a small 24VDC @
600mA supply, (Order #750-00004), suitable for bench-top experimentation with the Stamp PLC. If
you are installing the Stamp PLC for use in the field, be sure to properly size your 24VDC supply to match
the entire load, including digital outputs. The small 24 VDC supply offered by Parallax is not suitable for
most field installations as it does not supply sufficient current to power most output devices.
Do not use an AC supply, doing so will damage the Stamp PLC and void the warranty.
To install the power supply issued by Parallax, remove it from its packaging and cut off the 2.1mm power
connector.
supply. The striped wire is the positive lead. Connect the positive lead of your power supply to the +24
VDC pin. Connect the negative lead to the adjacent terminal labeled GND. When completed, your power
supply connection should resemble the image in Figure 7.
If you are using a different supply, follow these instructions: ensure the power supply is off, connect the
positive lead of your power supply to the +24 VDC pin, connect the negative lead to the adjacent
terminal labeled GND.
