(1) Relay driver module. (2) Relay board (optional).Note: Only the latest generator set controls (GSC) have the relay driver module (RDM) capability. Earlier 123-6004133-6350136-3870 EMCP Electronic Controls do not have the RDM capability. On the latest GSC's, setpoint SP11 must be programmed to the value 9. This tells the GSC to provide serial data at the spare output. See Systems Operation, "Spare Input/Output Programming OP6".The relay driver module (RDM) is an optional module that can be used to expand the number of available outputs on the GSC. The RDM outputs are controlled by the customer communication module (CCM). For use by the customer, the RDM provides nine additional outputs. The RDM outputs are individually controlled by a serial data link from the GSC. These outputs may drive the optional relay board or these outputs can be directly connected to horns, lamps, or other devices. The relay board contains nine relays. Each relay has one set of NO and NC contacts for use by the customer. These relays are distinct from the seven relays contained with
