Each Orbit 60 system requires a single System Interface Module (SIM)  The SIM

provides the user access to manage protection configuration, local display,

system-level diagnostics, system LEDs, system contacts, and the system

protection fault relay. The SIM occupies one slot and must be adjacent to the

Power Input Module (PIM) in the chassis.

The SIM is the access point for configuring and maintaining the system. The

module  communicates to the Orbit Studio configuration software and transmits

the configuration to other modules in the system. The SIM provides a physical

access security feature through a key-lock switch on the public side and a

contact on the utility side of the SIM. Either of these controls can be used to secure

the system configuration, preventing unauthorized changes.

The SIM has 3 independently configurable ethernet ports, each port can be used

for system configuration, system time synchronization, temporary

troubleshooting, or an external display.
