7B30 Rev. 0 is a small, low-cost signal conditioner that is suitable for a variety of applications including process control and factory environments. It accepts inputs from a range of transducers and provides a wide output voltage range over the industrial temperature range.
The 7B30 series signal‑conditioning modules provide isolated, voltage or current input handling, amplification, filtering and precision output ranging from +1 V to +5 V or 0 V to +10 V. They are hot‑swappable, support a wide supply range (+14 VDC to +35 VDC) and offer up to 1500 V rms continuous common‑mode isolation.
The handbook includes functional block diagrams, pin configuration tables, mechanical dimensions, environmental ratings and detailed specifications such as non‑linearity, accuracy, bandwidth and protection features, enabling integration into industrial process‑control and data‑collection systems.
