Issue
Is it possible to use the RP-C relays to control LED Light? The specification sheet does not specify the maximum inrush current.
Product Line
EcoStruxure Building Operation
Environment
- Building Operation Room Controller (RPC) 24 V
- Building Operation Room Controller (RPC) 230 V
Cause
RP-C is not designed for switching light loads, and especially not LED loads.
LED loads will result in a very high inrush current and require relays that are designed for that.
Furthermore, the light application often requires relays that keep the light on in case of power failures which is not the case for RP-C.
Resolution
The CRS light modules and the Hotel Relay modules have that type of relays and can handle peak currents up to 800A, which is typical for LED loads. If using the CRS modules is not an option for the customer another possibility is to use a contactor connected to the RP-C.
