How to supply the power correctly
•
Refer the pin map of power RTB before wiring.
•
Current capacity margin should be considered when you supply the power.
•
Supply voltage 24Vdc which is recommended voltage level.
•
System and Field power must be supplied separately as the picture above.
•
If the power is supplied to each System and Field power from same power source, it would
be vulnerable to power noise.
