There are two ways in which Sensor Seal Gateways can be powered:
- Power over Ethernet (PoE) 12V to 57V DC
- 12V to 48V DC through the power terminals.
The Sensor Seal Gateway draws less than 5 watts of power and has a wide input voltage range, making it ideal to power from a wide variety of power sources.
Powering via PoE
To power a Sensor Seal Gateway via PoE, you will need a
PoE injector
. The Sensor Seal is a passive PoE
device, meaning that it does not negotiate the voltage level and may not be detected by active power sourcing equipment (PSE). We recommend using a 24-48V passive PoE injector (mains or DC supplied) with the Sensor Seal Gateway.
Connect the PoE output of the PoE injector or switch to the Ethernet port of the Gateway using a suitable network cable. When powered, the orange
Power
LED on the Gateway will light up.
Powering via Power Terminals
To power a Sensor Seal Gateway via its power terminals, you will need a suitable DC power source that has an output voltage of between 12V and 48V. Connect the positive terminal of the power source to the
+
terminal on the Gateway and connect the negative terminal of the power source to the -
terminal on the Gateway.
When powered, the orange power LED on the Gateway will light up.
Warnings and Considerations
- Ensure the power source provides a stable, clean output voltage
- Exceeding the maximum input voltage of 57V may damage the device
- When using a long network cable, a PoE voltage of at least 24V should be used
- If the gateway fails to be powered by an active PoE injector, ensure the port's ouput is manually forced on or use a suitable passive PoE injector.
- Do not let the power supply screw terminal wires come into contact with the RX, TX, or IO terminals or any other part of the gateway. This will cause permanent damage to the gateway when powered.
