Do not combine 24/ 48 V systems with high voltage systems.
9.6 OPC24VPS 24V DC External Supply Module
External 24 V DC Supply
An external 24 V DC supply can be installed for low-voltage supply to the control card and any option card installed. This enables full operation of the Keypad
(including the parameter setting) without connection to mains.
External 24 V DC supply specification:
Input voltage range
24 V DC
±
15 % (max. 37 V in 10 s)
Max. input current
2.2 A
Average input current for AF-650 GP
0.9 A
Max cable length
75 m
Input capacitance load
< 10 uF
Power-up delay
< 0.6 s
The inputs are protected.
Terminal numbers:
Terminal 35: - external 24 V DC supply.
Terminal 36: + external 24 V DC supply.
Follow these steps:
1.
Remove the Keypad or Blind Cover
2.
Remove the Terminal Cover
