10.4.2 Protection Function
10.4.2.1 Protective Functions
0011-3329
iR7105 / iR7095 / iR7086
The machine is designed to automatically stop the output of the DC power supply as soon as the overcurrent protective mechanism turns on.
If an overcurrent is detected by the overcurrent detection circuit A, outputs [1] and [2] are stopped; this is to prevent malfunction of the machine, as output [1] is
used by the logic system.
If the overcurrent detection circuit B detects an overcurrent, output [2] is stopped.
PCB
Description
DC power supply PCB
- generates DC power from AC power
- protects against over-current
Relay PCB
- generates DC power from DC power (24 V to 18 V)
- supplies DC power to loads
- protects individual loads against over-current
