Relay Protection
Each relay circuit must be fused externally to protect the
relay and the load. Modules are also fused internally with
factory - replaceable fuses to protect the I/O assembly and the
module’s printed circuit board.
If an inductive load is connected, a suitable snubber must be
externally provided.
