Comfort Local Expansion Modules (LEM) provide additional inputs and outputs to Comfort main panels or slave panels.
LEM02-M2 provides 8 additional inputs but no additional outputs. Adding an OP1 to the LEM02-M2 provides an additional 8 outputs (in effect turning the LEM02 into an LEM01-M2).
The Local expansion modules are connected locally to the Comfort main panel or slave expansion Panel via a short 10-way ribbon cable to socket J5. The board is mounted within the main panel using the four fixing posts and screws provided, or it can be mounted on the base of the Comfort enclosure using an optional longer ribbon cable. Hence only 1 LEM can be connected to Comfort or SEM.
When more than 16 Inputs and Outputs are required, Slave Expansion Panels (with Enclosures) are required. These are the same size as Comfort and have their own power supply and battery charger to supply auxiliary power to external devices.
