CLIPSAL C-BUS 4 Channel Relay L5504RVF20 - Intermittent Fault

Intermittent working condition.

The internal power supply is on it's way out, and it's impedance isn't what it's supposed to be, which leads to intermittent spurious communication on the entire bus.

This means it could intermittently cause lights and appliances on the bus to turn on or off randomly.

While not recommended for permanent installation, this could be useful as a short term replacement, for testing and experimenting, or CBUS on a tight budget.
