Product Q&A
- Q: Does the USIO21 require separate power for I/O?
- A: Yes, an external 24V DC power source is required to drive the field-side sensors and actuators.
- Q: Is the output type NPN or PNP?
- A: The USIO21 typically utilizes a sink-type (NPN) transistor output configuration.
- Q: Can it be used with the V2000 or V3000 controllers?
- A: Yes, it is compatible with the standard V-Series unified controller backplane architecture.
- Q: Are there status indicators for each point?
- A: Yes, the front panel features an LED array for real-time monitoring of both input and output status.
