          FAQ

          • What functional purpose does the 125800-01 module serve within the Bently Nevada 3500/25 Enhanced Keyphasor architecture?
            125800-01 is a Keyphasor I/O module with internal terminations that receives raw analog transducer signals from proximity probes or magnetic pickups and conditions them into digital Keyphasor timing pulses used as phase/timing references by 3500 monitoring modules.
          • How does the signal interface of 125800-01 accommodate shaft-timing transducers for high-resolution phase detection?
            The 125800-01 accepts Keyphasor input signals from eddy-current displacement probes or magnetic pickups, converting once-per-revolution or multi-event per revolution pulses into digital timing references that support accurate shaft speed and phase measurement in the 3500 system.
          • How many channels does 125800-01 support, and what does this mean for multi-sensor configurations?
            The 125800-01 provides two buffered input channels for Keyphasor or timing transducers, enabling dual-sensor redundancy or multiple reference signal acquisition in a single half-height slot.
          • What are the electrical input and output characteristics of 125800-01, and how do they influence interfacing with field devices?
            125800-01 typically accepts input signals in the range of +0.8 V to –21.0 V DC for non-isolated configurations, and its buffered outputs feature a maximum impedance of ~504 Ω, ensuring robust drive capability for downstream monitoring modules.
          • What are the typical power consumption and environmental limits of 125800-01 in industrial deployment?
            The 125800-01 has a nominal power consumption of ~3.2 W and is designed to operate reliably within a broad industrial range (e.g., ~0 °C to +65 °C with non-condensing humidity), making it suitable for high-availability rotating machinery monitoring applications.
          • In what ways does 125800-01 support legacy compatibility and system upgrades?
            As part of the 3500/25 Enhanced Keyphasor family, 125800-01 maintains electrical and mechanical backward compatibility with previous Keyphasor modules, allowing seamless upgrades in existing 3500 installations without reengineering existing signal plant cabling or diagnostics logic.
