DC Current Transmitter Transformer Transducer Split Core 0-50A to 0-10V
Input: 0-50A DC, Output: 0-10V DC, Power Supply: 24V DC +/-15% (alternative 12V available on request). This model is suitable for simple voltage-based monitoring in control systems and data collection workflows. It is best for technicians who need a straightforward 0-10V signal for analog input channels and quick clamp-on installation.
Best for: small to mid-range DC circuits where a linear 0-10V signal is required for chart recorders, DAQs, or PLC analog inputs. It’s chosen for moderate current needs and straightforward interfacing.
Caution: Check that your DC supply matches the 24V DC requirement; if the site uses a different supply, request the alternate 12V option to avoid measurement drift.
FCS521-SP-5V AC Current Transducer
Output: 0-5V DC from an AC input range of 0-50A. Split-core design enables installation without disconnecting wiring, which minimizes downtime in busy systems. It features high isolation and low power consumption for reliable operation in industrial environments.
Best for: automation setups that use PLCs or ADCs requiring a 0-5V input, or digital meters needing a compact, quick-install transducer. This model excels where rapid retrofits are necessary.
Limitation: It measures AC current; for pure DC applications, another DC-specific model may be a better fit to ensure signal compatibility and performance consistency.
DC Current Transmitter 0-200A 4-20mA
Input: 0-200A DC, Output: 4-20mA DC, Power Supply: 24V DC +/-15% (If you need another power such as 12V, contact us). This transducer is ideal for existing 4-20mA loops, enabling currents to be monitored over longer distances with minimal signal loss.
Best for: process control environments that rely on current loops for sensing remote signals or when integrating with legacy 4-20mA instrumentation. Choose this if your system already uses 4-20mA wiring and you need compatible input ranges.
Caution: The 4-20mA signal must be loop-powered and correctly terminated; verify wiring to avoid offset errors in long cable runs.
DC Current Transmitter 0-200A 0-10V
Input: 0-200A DC, Output: 0-10V DC, Power Supply: 24V DC +/-15% (Alternative 12V available on request). This option provides a voltage-based signal suitable for analog inputs on data loggers or PLCs that prefer a 0-10V range.
Best for: projects needing direct 0-10V voltage sensing from higher current DC sources, particularly when data logging or graphing current trends is essential. It’s a natural fit for analog interface applications.
Limitation: Ensure your analog input has enough headroom to accommodate the 0-10V span under peak load conditions.
DC Current Transmitter 0-800A 4-20mA
Input: 0-800A DC, Output: 4-20mA DC, Power Supply: 24V DC +/-15% (If you need other power such as 12V, contact us). This high-current option supports large industrial equipment and heavy-duty monitoring, preserving compatibility with standard 4-20mA loops.
Best for: heavy machinery or power systems where current levels can approach 800A, and a robust 4-20mA signal is preferred for reliability across long distances or noisy environments.
Limitation: The greater the current range, the more attention needed on isolation and wiring quality in high-current installations to avoid interference.
Buying Guide: Choosing The Right Split Core DC Current Transducer
What output signal do you need? Decide between 0-10V, 0-5V, or 4-20mA based on your data acquisition system, PLC inputs, or measurement instrumentation. Voltage outputs suit ADCs and DAQs, while current outputs integrate smoothly with existing 4-20mA loops.
What is your current range? Select a model that covers your maximum anticipated current with margin. For very high currents, a model up to 800A helps reduce the need for multiple sensors.
AC vs DC compatibility: If your application uses DC only, prefer DC-rated transducers. Some models in this list handle AC current inputs; verify compatibility with your system’s source.
Installation considerations: Split-core/clamp-on designs offer quick mounting without disconnecting conductors. Ensure the device’s isolation rating, insulation class, and enclosure suitability match the installation environment.
Power supply: Many units run on 24V DC, with options for 12V. Confirm your available supply and consider any needed wiring adaptations or voltage regulators.
Signal integrity: For long cable runs, 4-20mA signals often provide better noise resilience than voltage outputs. Plan for proper termination and shielding where necessary.
