PR 4179 Universal AC / DC Transmitter

The PR 4179 Universal AC / DC Transmitter is a cutting-edge industrial signal conditioning module that accurately measures and converts AC current and voltage signals into reliable unipolar or bipolar DC process outputs. Ideal for demanding automation, energy monitoring, and process control applications, this transmitter supports input ranges up to 0-5 A AC RMS and 0-300 V AC RMS. Thus, the 4179, from PR electronics, enables precise measurement of current transformers, supply lines, and power circuits.

• The 0-5 AAC RMS range makes it possible to accurately measure a typical current transformer.
• The 0-300 VAC RMS range allows accurate supply voltage monitoring.
• The PR 4179 measures standard input ranges and can be freely configured to customer-defined input range. 
• Converts narrow AC current / voltage inputs to wide bipolar or unipolar outputs, for example, 0-1 VAC RMS input = ±10 volt or 4-20 mA output with a minimum span of 0.5 AAC RMS or 0.5 VAC RMS.
• Configurable input limits control the output value for safety improvements.
• The 4179 Universal AC / DC Transmitter provides the required failure data (SFF and PFDAVG) for SIL 2 applications as per IEC 61508 / IEC 61511.
• Failure rates for PR 4179 correspond to Performance Level "d" according to ISO-13849.

PR 4179 Universal AC / DC Transmitter from PR electronics

With universal power supply compatibility (21.6-253 VAC / 19.2-300 VDC) and a response time of less than 0.75 seconds, the PR 4179 Universal AC / DC Transmitter delivers fast, accurate signal conversion with better than 0.3 % accuracy. Its flexible output configuration includes active or passive current outputs, thus enabling seamless integration into PLCs, DCS and data acquisition systems.

Ideal for industrial immunity, the 4179 meets NAMUR NE21 and NE43 recommendations, providing excellent noise rejection as well as reliable detection of input errors in harsh EMC environments. Robust 3-port galvanic isolation (2.3 kVAC) protects equipment and also ensures signal integrity.

• The latest analog and digital techniques obtain maximum accuracy and immunity to interference.
• Possibility of output safety feedback by selecting S4-20 mA output.
• The current output can drive up to 800 Ohms, with an adjustable response time of 0.0-60.0 seconds.
• Exceptional mA output load stability of <0.001% of span / 100 Ohm.
• Meets the NAMUR NE21 recommendations, thus ensuring high accuracy in harsh EMC environments. 
• Meets the NAMUR NE43 recommendations, allowing the control system to easily detect an input error.
• Tested to a high 2.3 kVAC, 3-port galvanic isolation level.
• Excellent signal to noise ratio of > 60 dB.

Easy Mounting, Installation, and Programming

Configuration, process monitoring, and diagnostics are easily achieved via the detachable PR 4500 display, while advanced safety features support SIL 2 and PL "d" applications. Whether monitoring AC power systems, converting sensor outputs, or driving control loops, the PR 4179 enhances precision, reliability, and operational uptime in industrial automation networks.

• Very low power consumption means units can mount side by side without an air gap – even at 140˚F (60˚C) ambient temperature.
• Configuration, monitoring, 2-point process calibration, and more are available using PR's 4500 series of detachable displays.
