The modules RLM5200 and RLM5252 can be used for signalising operation-, status- and fault- messages like fire dampers, frost, filters, fan belt etc. The RLM5200 module is equipped with 5 Duo-LEDs and the RLM5252 provides 10 Duo-LEDs. You can trigger each color of each LED separately, because they are wired to discrete clamps. Therefore, the states "Fault" and "Run" can be signalized in one single LED. For the red LEDs you can choose between the NO contact and the NC contact principle by the means of jumpers. The green LEDs can only be triggered in the NO contact principle. Yellow and red LEDs cause a collective fault message via the plug-in 5-pole bus system on the collective fault module RSM. There are two group outputs (+24V DC) for creating different priority levels (group 1 = LED 1-5, group 2 = LED 6-10), which are activated by red or yellow coded inputs. You can trigger a lamp test over the plug-in 5-pole bus system with the RSM... module.
