PR 3114 Isolated Universal Converter

The PR 3114 Isolated Universal Converter is a versatile, high-performance signal conditioning module that's ideal for industrial process control and measurement applications. Acceptable with a wide range of inputs, including RTDs, thermocouples, ohmic sensors, potentiometers, milliamps, and voltage signals, this converter, from PR electronics, transforms virtually any analog sensor signal into isolated current or voltage outputs suitable for PLCs, DCS, and SCADA systems.

• Linearized, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a standard analog current / voltage signal, for example, from solenoids and butterfly valves or linear movements with attached potentiometer.
• Power supply and signal isolator for 2-wire transmitters.
• Process control with standard analog output.
• Galvanic separation of analog signals and measurement of floating signals.

PR 3114 Isolated Universal Converter from PR electronics

With robust 3-port galvanic isolation rated at 2.5 kVAC, the 3114 Isolated Universal Converter delivers exceptional protection against ground loops, electrical noise, and transient disturbances, thus safeguarding both measurement integrity and control equipment. Its slim 6.1 mm housing enables high-density DIN-rail mounting, up to 163 units per meter, making the PR 3114 ideal for space-constrained panels.

• A green front LED indicates normal operation and malfunction.
• Continuous check of vital stored data for safety reasons.
• 2.5 kVAC, 3-port galvanic isolation.

Easy Programming, Mounting, and Installation

Advanced configuration and diagnostics are available via detachable communication interfaces and the PR 4590 ConfigMate, eliminating the need to open the unit for DIP-switch programming and allowing password-protected setups. Continuous internal data validation and a front-panel status LED further enhance reliability and ease of use. With certification for safe area and hazardous locations (FM Div. 2, ATEX/IECEx/UKEX Zone 2), as well as marine applications, this isolated universal converter excels in temperature measurement linearization, resistance signal scaling, transmitter isolation, and general analog signal conditioning across demanding industrial environments.

• Configuration, monitoring, and diagnostics using PR 4500 detachable communication interfaces via the PR 4590 ConfigMate.
• As the 3114 features electronic hardware switches, it is not necessary to open the device for setting of DIP-switches.
• Password protection available for all programming.
• Scrolling help text in 7 languages.
• Units can mount side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 158˚F (70˚C) ambient temperature. 
• Units can be supplied separately or installed on PR 9400 power rail.
• The narrow 6.1 mm housing allows up to 163 units per meter.
