3B16 series precision signal conditioning modules are used for converting analog transducer signals into digital signals. It can be used for industrial signal conditioning, industrial signal isolation, industrial signal filtering and other scenarios.
The 3B16 is a single‑channel signal‑conditioning module that interfaces, amplifies and filters signals from 4‑arm full‑bridge strain‑gage bridges (300 Ω – 1 kΩ). It provides a constant +10 V bridge excitation and simultaneous precision voltage (0‑+10 V) and current (4‑20 mA) outputs, with hot‑swappable, mix‑and‑match design for easy field calibration.
The handbook includes functional block diagrams, pin‑out tables, mechanical dimensions, environmental limits and detailed specifications such as accuracy (+0.1 %), isolation (+1500 V peak), bandwidth (0.1 Hz‑10 Hz input, 100 kHz output) and power requirements (+24 V loop supply).
| Bridge excitation voltage | +10 V |

The module provides a constant +10 V bridge excitation voltage.
It provides two simultaneous high‑level analog outputs: 0‑+10 V (or ±10 V) and 4‑20 mA (or 0‑20 mA).
Yes, the modules are hot‑swappable under full power and can be interchanged without disrupting field wiring.
