Power Supply Specifications
Desktop Models
If you are providing a power supply for a desktop IOLAN model, your power supply must meet the
following requirements:
z
Output between 9-30V DC.
z
DC barrel connector: The cable attached to the power supply should be about 20AWG, length 6
feet approx. The barrel dimensions of the cable-plug are OD=5.5, ID=2.1, and length= 9.5mm,
with a straight barrel, and positive polarity on the inside and negative polarity on the outside.
z
Power can also be provided by:
z
Serial Port 1, pin 1 on the DS/SDS1 models
z
Serial Port 2, pin 1 on the SDS2 model
z
Serial Port 4, pin 1 on the SDS4/SCS4 models
z
Ethernet on the P series models (Power over Ethernet)
Power Over Ethernet (PoE) Models
The 1-port/4-port SDS P models can be powered by either the external DC power supply (included)
or PoE or both. The 2-port SDS P does not accommodate an external power supply and can be
powered only through PoE.
The IOLAN SDS P model is considered a Powered Device (PD) and can only accept power from an
IEEE 802.3AF compliant Power Source Equipment (PSE) device. The IOLAN PoE can receive up to
13W of power using one of the following methods to connect to a PSE:
z
Using the two unused twisted pair wires (10/100Mb only).
z
Using the two data pairs or "phantom power" method (100Mb).
I/O Models
The power supply for a desktop IOLAN I/O model must meet the following requirement:
z
Output between 9-30V DC and a minimum of 600mA current.
Note:
The maximum load for the Relay channel is 1A @ 30VDC or 0.5A @ 120VAC.
