Modules
• All modules are accessed through the front of the enclosure.
• I/O modules can be removed and replaced without disturbing field wiring.
• Each printed circuit board (PCB) fits into a guide in the enclosure side panels.
• Each daughter board has self-aligning connectors to ensure correct insertion.
• All PCBs of different types are keyed to prevent improper insertion into the
wrong location.
