Reliable Analogue Signal Conversion for Industrial Automation
Current-to-voltage conversion is commonly required when industrial sensors, transmitters and other field devices provide a current signal while the receiving control or measurement equipment requires a voltage input. By incorporating a precision 500 Ω resistor, the BNMS-CA-I/U-500 provides a simple passive method of converting standard analogue current signals into proportional voltage signals.
The 500 Ω resistance is particularly suited to industrial analogue interfaces, allowing a 0–20 mA current signal to produce a corresponding 0–10 V voltage signal. A standard 4–20 mA signal produces a proportional 2–10 V output. The compact plug-in format helps simplify control panel wiring while providing a precise interface between field instrumentation, PLCs and automation equipment.
Typical Applications
- PLC analogue input and output interfaces.
- Industrial sensor and transmitter signal conditioning.
- 0–20 mA to 0–10 V analogue signal conversion.
- 4–20 mA to 2–10 V analogue signal conversion.
