CHARMs Smart Logic Solver specifications

Installation notes

Redundant CHARMs Smart Logic Solvers (CSLS) install on the CHARMs Smart Logic Solver Carrier.
The CSLS receives 24 VDC input power from the CHARMs Smart Logic Solver Carrier.
The CSLS connects to the Local Safety Network through redundant Ethernet ports on the CHARMs Smart Logic Solver Carrier.
A physical keylock switch on the CHARMs Smart Logic Solver Carrier along with an unlock software function restricts how and when the CSLS can be unlocked for downloads and upgrades.

Table: CHARMs Smart Logic Solver specifications
