The LightLEEDer Addressable Relay Driver Module consists of the electronics that drives the R40 relays. This driver module is addressable, so relay numbering can be on the left side or the right side only, or on both sides. Each module has built in optical isolation and is designed to control up to 4 single pole relays per side. Each 4-relay side output is independently addressed, giving you the flexibility to number them as needed. They are provided with push-on type connectors with no wires to terminate. Modules are also available in a remote mount option, which could eliminate a controller in another panel to reduce cost. Every module has power and communications status LED indicators for easy diagnostics.
