          FAQ

          • What exactly does the 125680-01 Proximitor I/O Module do within the 3500/40M Proximitor Monitor environment?
            The 125680-01 module serves as the Proximitor I/O interface for the 3500/40M Proximitor Monitor, receiving signals from up to four proximity transducers and conditioning them for dynamic measurement of vibration, shaft position, and displacement parameters, which are then used for real-time machinery protection.
          • How many sensor channels does 125680-01 accommodate, and what is the input impedance for these channels?
            The 125680-01 supports 1 to 4 proximity transducer channels, with a standard input impedance of 10 kΩ for each channel. When Triple Modular Redundancy (TMR) I/O is used, the effective impedance of three bussed channels in parallel is approximately 50 kΩ.
          • What are the required electrical characteristics for a proximity sensor connected to 125680-01?
            The module delivers a -24 Vdc transducer power supply and typically consumes around 7.7 W. Buffered transducer outputs have an output impedance of approximately 550 Ω, ensuring reliable signal buffering for subsequent processing.
          • What signal conditioning performance and filtering capabilities does 125680-01 provide?
            The Proximitor I/O module’s signal conditioning includes user-programmable filters such as direct and gap filters. Typical direct (displacement) filtering has a -3 dB frequency at 1.2 Hz, while gap filters may have a -3 dB point around 0.41 Hz. This allows optimization of measurement bandwidth for either slow or fast machinery dynamics.
          • What diagnostics and status indications are available on the 125680-01 module’s front interface?
            Status LEDs on the front panel of the 3500/40M system (associated with the 125680-01 module) include indicators for OK (module health), TX/RX (communication activity), and Bypass (bypass mode), facilitating quick visual diagnostics at the rack level.
          • What types of machinery and monitoring applications is 125680-01 typically deployed for?
            125680-01 is used in continuous machinery protection systems for rotating equipment such as gas turbines, steam turbines, compressors, pumps, and generators. Its precision monitoring supports early fault detection, predictive maintenance, and compliance with high-reliability protection standards.
