CHARM Baseplate specifications

Installation notes

The CHARM Baseplates hold CHARMs and install directly onto a vertical T-type DIN rail. CHARM Baseplates connect to the CHARMs I/O carrier and to other CHARM Baseplates through connectors on the baseplates.
Each CHARM Baseplate holds one Address plug and up to 12 CHARM terminal blocks holding CHARMs.
Connect the CHARM Baseplate with Address Plug 1 to the CHARMs I/O carrier as shown in Figure: Connected CHARM Baseplates.
Install CHARM Baseplates in sequential order under the CHARM I/O carrier based on the Address Plug installed on the baseplate. Connect the baseplates together to form the power and communications bus for CHARMs.
Up to eight CHARM Baseplates can be installed under one CHARM I/O carrier.
Any mix of CHARM terminals can be installed on a CHARM Baseplate; however, if CHARM Fused Injected Power Terminal Blocks are installed on a CHARM Baseplate they must all be of the same voltage.
