G7E-RTCA

Description

RTC / alarm option module (real-time clock) for G7E / K120S series expansion; provides timekeeping and alarm/timestamp functionality for GLOFA/Master-K variants.

The Polar Energy Assessment:

The G7E-RTCA is an option pack providing a real-time clock and alarm/timestamp functions for G7E / K120S family controllers and expansion racks. It’s not a CPU; it’s an accessory that supplies time reference and alarm/event timestamping for processes that need logged time data or time-based control features. Reseller listings and LS product tables list it as an add-on option for the G7/G7E family.

Pros

• Adds RTC and alarm/timestamping without reworking PLC program structure.
• Small, cheap option to enable time-based logging and scheduling.

Limitations

• Accessory; requires compatible main module/CPU; check compatibility (G7/G7E / K120S family).
• Doesn’t replace a historian or full data-logging solution for high-volume needs.

Typical use cases

• Event timestamping, scheduled operations, shift-based logging, and alarm timestamp records for traceability.
