PR Electronics 4 Series Signal Conditioner with Current/Voltage Input and Output, 300V DC Supply, Zone Certified, Model 4184

PR Electronics 4184 is a 4 Series Signal Conditioner designed for precise conversion of DC current and voltage signals to wide bipolar or unipolar outputs. It interfaces analog active signals and powers 2/3-wire transmitters from sensors measuring parameters such as pressure, flow, level, torque, position, and acceleration, making it an ideal component for industrial automation, process control, and instrumentation systems.

This model supports input signals ranging from 0 to 100%, ±100 mA currents, and voltages up to ±300 V DC, converting these into precise output signals of ±10 V or ±23 mA current. It is universally powered by a 300V DC supply, with a 3-port galvanic isolation rated at 2.3 kVAC, ensuring robust operational safety and signal integrity in demanding EMC environments.

The 4184 is engineered to operate continuously in temperatures from -20°C to 60°C and installs conveniently on DIN rails with screw terminal connections. The unit carries certifications for hazardous area use including Zone, EAC, FM, ATEX, IECEx, UL, and DNV GL approvals, making it suitable for use in industrial and marine environments where safety and compliance are paramount.

Its fast response time (< 20 ms) and exceptional output stability (only 0.001% of span/100 ohm deviation) enable reliable and accurate signal transmission even under varying load conditions. Moreover, it is designed to comply with NAMUR NE21 (burst noise immunity) and NE43 (sensor error detection) recommendations, providing advanced diagnostic capabilities.

Programming and configuration of the 4184 transmitter is facilitated by the PR 4501 detachable display module, which offers a user-friendly interface with a 4-line LCD, password protection, and functions including 2-point calibration, process simulation, and detailed diagnostics.

Overall, the PR Electronics 4184 Signal Conditioner is suited for industrial automation, laboratory instrumentation, manufacturing process control, and hazardous area applications requiring precise, stable, and safe signal conditioning.

Supports DC inputs up to ±300 V and ±100 mA currents with high precision. Buffered voltage and both passive and active current output options. Operates with a 300V DC supply for hazardous area compatibility. DIN rail mounting with screw terminals and IEC IP20 protection.

Certified for multiple hazardous area approvals including Zone, ATEX, IECEx, UL, and DNV GL. Fast response below 20 milliseconds and excellent output load stability. Meets NAMUR NE21 and NE43 standards for signal quality and sensor diagnostics.
