Bently Nevada 1701/25 161141-01 Seismic Input Monitor Module (FieldMonitor series)

FAQ

Q1: What is the main function of the 1701/25 – 161141‑01 monitor?
A1: It monitors vibration (seismic) signals from acceleration or velocity transducers, processes them with filtering and signal algorithms, compares against Alarm thresholds, and outputs status to a host system.

Q2: How many channels does it support and can it mix velocity and acceleration on one module?
A2: It supports 2 independent channels. You cannot mix velocity and acceleration on one channel; each must be configured separately.

Q3: What filtering and measurement modes are available?
A3: The module allows programmable high‑pass and low‑pass filters; measurement modes include direct, RMS, integrated, filtered direct, filtered RMS, etc., depending on configuration.

Q4: What are the physical dimensions and weight?
A4: The module measures approximately 127 mm × 21.6 mm × 105 mm and weighs about 0.314 kg (0.69 lb).

Q5: What is the power and consumption specification?
A5: It operates with –24 V DC and +5 V supplies, consuming approximately 1.5 W excluding transducer power.

Q6: What is the operational temperature range?
A6: It is rated to operate between –20 °C and +70 °C, and for storage between –40 °C and +85 °C.

Q7: What kind of fault detection does the monitor support?
A7: It includes embedded self‑tests that can detect monitor integrity problems or transducer issues and output a “NOT OK” status.

Q8: Can outputs from both channels be used for trending or host interfacing?
A8: Yes — the module provides buffered processed signals for host system integration, enabling trending, diagnostics, or control interfacing.
