Gocator Snapshot Sensors: User Manual
Specifications • 544
Specification Value
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 on page 546.
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..
Encoder
Master 810 and 2410 support the following types of encoder signals:Single-Ended (5 VDC, 12VDC) and
Differential (5 VDC, 12 VDC).
For 5 VDC operation, pins 2 and 3 of each channel are used.
For 12 VDCoperation, pins 1 and 3 of each channel are used.
The 5-volt encoder input supports up to 12 volts for compatibility with earlier Master network
controllers. However, we strongly recommend connecting 12-volt output encoders to the
appropriate 12-volt input to attain maximum tolerance.
