A bundled connector plug (MC1,5/3-ST-3,5, Phoenix Contact. Suitable wire: AWG28 - 16) can help
you to connect the external power supply.
When you using this MC1,5/3-ST-3,5 plug to connect the external power supply, please strip the end of
the corresponding wire, insert it into the connector plug, then fix the screw to secure.
There is an optional AC adapter available from CONTEC.
Accessories (Optional):
AC adapter (Input: 90 - 264VAC, Output: 5VDC 2.0A): POA200-20
-
When using the internal power supply:
The terminal can provide the maximum power supply of +5VDC, 1.2A.
(Up to 2A of current can be supplied from analog board and this terminal consums a total
of 0.8A current)
-
When using the external power supply:
The terminal can provide the maximum power supply of 5VDC, 2A.
CAUTION
-
To use the AC adapter, please connect it to the terminal first, then plug the AC adapter into a outlet.
-
When the terminal is not used, please leave the AC adapter unplugged.
-
Continuously using the AC adapter under high temperature environment will affect its life.
-
Use the AC adapter not in a closed place but in a well-ventilated place. The AC adapter heats up
itself when loaded heavily. If the AC adapter is exposed to high temperature or used continuously,
you should keep the load at about 80% of the maximum load.
