All Digital IOs are 3.3 V LVTTL CMOS logic and can be used for data rates up to 20 Mbps.

* This is a +3.3 V supply that can provide up to 250 mA for external use.
The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

** Can be configured as 5.0 V CMOS logic. Upon request only, please contact sales@synapticon.com

*** This is a +5 V supply that can provide up to 250 mA for external use.
The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

Note

Each Digital IO needs to be configured as a Digital Input or Output via object 0x2210 (“GPIO”).
The object can also be used to activate a pull-down resistor.

Changes may require to powercycle the servo drive.

How to connect a temperature sensor

There is no particular input for temperature sensors in Node. Four analog inputs are available. Any of these can be used to measure the temperature sensor resistance. But the single-ended (AI 1, AI 2) is more accurate than the differential inputs (AI 3, AI 4) because the voltage difference is less. A simple circuit with an extra resistor for voltage dividing has to be implemented externally. For details about using temperature sensors please check our System integration guide.

Attaching a voltage divider

A voltage divider is needed when the Analog In needs to be calibrated. This is required for adjusting the measuring range when using a temperature sensor.

The image below depicts how to connect an RTD sensor resistance using the single-ended analog input.

../../../../../../_images/temp_volt_div_node_details.png

The internal resistance R i of the single-ended analog input is 20.4 kΩ and it is connected in parallel to the RTD sensor.
