PLC-7500
Power Line Carrier Set
The PLC-7500 combines the standard functionality of legacy transmitter/receiver sets with a modern, diagnostics‑rich design. It delivers unmatched visibility into your PLC channel by capturing time‑stamped events, trending key parameters, and offering on‑demand spectral analysis, so you can commission faster, extend maintenance cycles, and troubleshoot with confidence.

Built‑In Legacy Functions, Modern Design
The PLC-7500 is a state-of-the-art Power Line Carrier set that combines all the standard functionality of legacy transmitters/receivers with a comprehensive set of enhanced features not available on any other carrier set. It supports ON/OFF and FSK applications and adds deep insight through real‑time and event‑driven measurements. Backed by 25 years of expertise in measuring, aligning, and monitoring power line carrier systems, the PLC‑7500 delivers the visibility utilities need, with one‑touch access to critical information on a large front‑panel display, without sacrificing simplicity.
Unmatched Event Visibility
Legacy devices typically store only 3,500 to 5,000 events before critical data is overwritten. The PLC‑7500 records up to 32,768 time‑stamped events with triggers on frequency, level, reflected power, impedance, and phase. Trend level, reflected power, impedance, and phase with programmable sampling intervals as often as hourly to establish baselines for system integrity analysis. Capture and compare "as‑left" snapshots to extend maintenance cycles and reduce unnecessary truck rolls.
In legacy units, Checkback tests only report pass or fail. The PLC‑7500 adds depth by recording level, reflected power, impedance, and phase during each Checkback event, providing a clear picture of on‑off carrier channel health without requiring an outage.
Advanced Diagnostics, Included Standard
The PLC‑7500 is the only Power Line Carrier set that reports reflected power not only as traditional percent, but also in its polar components of impedance and phase. Percent reflected power provides only a simple magnitude, with no directional context about what is happening on the communication path. By contrast, knowing both impedance and phase delivers a new level of diagnostic clarity, simplifying alignment during commissioning and providing critical insight into changes on the communication path during troubleshooting.
Event‑driven or real‑time spectral captures provide immediate visibility during commissioning and mis‑operation analysis, allowing quick identification of stray or unexpected signals that could affect critical protection channels. Event‑driven captures are stored and can be retrieved directly on the front panel display for later review.
