Electrical Specifications

Some sensors require a minimum input voltage of 48 VDC. Verify the accepted input voltage for your sensor in the sensor's specifications; for specifications, seeSensors

Digital Input Voltage Range

Single-Ended Active LOW: 0 to +0.8 VDC

Single-Ended Active HIGH: +3.3 to +24 VDC

Differential LOW: 0.8 to -24 VDC

Differential HIGH: +3.3 to +24 VDC

For more information, see Input.

If the input voltage is above 24 V, use an external resistor, using the following formula:

 

R = [(Vin - 1.2V) / 10mA] - 680

When using a Master hub, the chassis must be well grounded.

The power supply must be isolated from AC ground. This means that AC ground and DC ground are not connected.

24 VDC power supply is only supported if all connected sensors support an input voltage of 24 VDC.

The Power Draw specification is based on a Master with no sensors attached. Every sensor has its own power requirements that need to be considered when calculating total system power requirements..
