Yokogawa 701270 Strain Input Module (NDIS)

The Yokogawa 701270 is a two-channel strain input module (NDIS) engineered for high-precision strain gauge measurements within Yokogawa's ScopeCorder data acquisition platform. It integrates with compatible NDIS bridge heads - such as the 701955 and 701956 - to deliver accurate static and dynamic strain analysis across industrial and laboratory environments.

Technical Specifications

Measurement Channels: Two channels per module Resolution & Sampling: 16-bit acquisition at up to 100 kS/s per channel Bridge Excitation: Selectable at 2 V, 5 V, or 10 V with electronic auto-balance capability Measurement Ranges: Strain measurements from ±500 µSTR to ±20,000 µSTR; supports mV/V inputs Accuracy: DC accuracy ±0.5% (strain); zero point accuracy ±(0.05% of 10 div) typical Frequency Response: 0.01 Hz to 200 kHz; bandwidth limit selectable at OFF/100 Hz/1 kHz/10 kHz in waveform observation mode Input Connector: NDIS connector (JSNDI-recommended standard)

Key Features

• Dual-channel configuration for simultaneous multi-point strain monitoring


• Electronic auto-balance reduces setup time and improves measurement stability


• Three selectable excitation voltages accommodate varied gauge impedance and sensitivity requirements


• 16-bit resolution provides granular data acquisition for transient and fatigue analysis


• Wide frequency response from 0.01 Hz to 200 kHz supports quasi-static and dynamic testing


• NDIS connector ensures compatibility with standardized instrumentation ecosystems

Typical Applications Strain measurement in materials testing, structural health monitoring, mechanical component evaluation, and load cell integration within high-speed data acquisition workflows.

Compatibility & Integration The 701270 module integrates directly into Yokogawa DL350, DL850 series, DL950, and SL1000 data acquisition systems. Operation requires a compatible NDIS bridge head (701955 or 701956) for signal conditioning and gauge excitation.
