PLC-RSC- 24DC/1/CB1-6 - Relay module


Notes | Notes on operation: Repeated hard short circuits can reduce the melting integral of the integrated backup fuse. A suitable flyback diode must be used when switching inductive loads If the DIP switches are not covered by an adjacent module, the PLC-ATP partition plate must be used for ESD protection The device contains components that can be damaged or destroyed by electrostatic discharge. When handling the device, observe the necessary safety precautions against electrostatic discharge (ESD) according to EN 61340-5-1 and EN 61340-5-2. The PLC-ATP separating plate should be installed for safe isolation between adjacent modules Do not connect adjacent channels to SELV/ PELV and voltages dangerous to the touch. At least one functional insulation against adjacent modules is complied with in the support rail direction. If the application has higher requirements on the insulation (basic or reinforced insulation), then these must be realized through suitable measures (e. g., partition plates). Do not use to separate SELV / PELV circuits from other circuits, because safe isolation is not guaranteed. |
