The Future of Carrier
PCM-5350
Power Communications Monitor
The PCM-5350 is an always-on monitor that provides deep, real-time visibility into PLC system performance. It serves as a permanent diagnostic window, helping you identify and analyze issues without the need to log into a transmitter-receiver or connect a test instrument.

The PCM-5350 is a five-channel, frequency-selective monitor designed for continuous, read-only observation of Power Line Carrier and Audio Tone protection systems. It captures real-time and event-driven measurements that help utility professionals diagnose mis-operations, evaluate system performance, and track gradual channel degradation over time. By providing full system visibility without requiring access to transmitters or receivers, the PCM-5350 supports secure, remote diagnostics and helps extend testing and maintenance cycles in alignment with NERC PRC-005 requirements.
Features
- Mult-Channel
- Monitor up to five channels, each programmable for Frequency, Bandwidth and Function Type (2- FSK, 3-FSK, ON-OFF or Noise).
- Spectral Analysis
- Capture event driven or real-time spectral analysis of the communication path. Event driven captures can record up to 400 ms of pre-event spectral data.
- Trending
- Trend reflected power, level & noise to monitor for gradual channel degradation.
- Flexible Alarming
- Program Alarm Outputs and Front Panel LED’s for any event type or program an alarm output for multiple event types.
- Event Recorder
- Record up to 32,000 time stamped events based on changes in frequency, level, reflected power & noise.
- Real-Time View
- Extend maintenance cycles by remotely accessing real-time measurements and a time stamped status report of all channels.
- Measurement Accuracy
- Accurate measurements of reflected power and level changes by installing between the last hybrid and line tuner.
- Remote Access
- The PCM-5350 cannot affect the existing protection system parameters (for example Guard & Trip frequencies). Designed to be your primary remote source for critical communication data.
Use Cases
- Mis-operation evaluation and diagnosis.
- Review captured in-band spectral analysis of trip/fault occurrence for noise intrusion.
- Accurately measure and monitor reflected power and level changes by installing between last hybrid and line tuner.
- Set alarms and record events for level and reflected power changes.
- Set out-of-band noise detection alarms.
- Initiate remote keying of ON-OFF carrier for capture of signal level and reflected power.
- Monitor Audio Tone Communication Circuits used for tone pilot protection.
