Notes
- Pin 1,2 for power supply AC(DC)85-265V.
- Pin 6,8 for measurement signal input, Make sure the product parameters on the label are the same to your order, if not, please contact BLUE JAY sales team, sales@cqbluejay.com.
- For input AC signal, there is no polarity difference. For input DC signal, Pin8 for positive (+); Pin 6 for negative (-).
- Output signal for 4~20mA, access pin 4 for positive (+); Pin 5 for negative (-).
Output signal for 0~5V, access pin 11 for positive (+); Pin 5 for negative (-).
! Do read and full understanding of the controller wiring, if cannot sure the connection, please contact BLUE JAY technical support tech@cqbluejay.com for more help.
