PR 3101 TC Temperature Converter

The PR 3101 TC Converter is a high-precision temperature signal converter for industrial automation, process control, and monitoring systems. This DIN-rail mountable signal conditioning module, from PR electronics, measures thermocouple (TC) Type J and K sensors and outputs a conditioned analog current or voltage signal compatible with PLCs, DCS, and data acquisition systems, providing accurate temperature conversion with excellent EMC performance and robust noise suppression.

• Temperature converter which measures standard TC J and K temperature sensors and provides an analog current or voltage output signal.
• All terminals are over-voltage protected, polarity protected and short-circuit protected.
• The device can mount in Safe area or in Zone 2 / Division 2 hazardous areas and features approval for marine applications.

With impressive flexibility, the 3101 features selectable fast (<30 ms) or damped (300 ms) response times to suit dynamic measurement or filtered applications. Furthermore, its pre-calibrated temperature ranges are easily selectable using intuitive DIP switches, with no external tools necessary. With accuracy better than 0.1 % of span, a signal-to-noise ratio over 60 dB, and compliance with NAMUR NE21 and NE43 standards, the PR 3101 TC temperature converter delivers reliable, repeatable results in electrically noisy environments.

• Flexible 24 VDC (±30%) supply via connectors.
• Excellent conversion accuracy in all available ranges, better than 0.1% of span.
• < 30 ms fast response time with simultaneous sensor error detection when selected.
• Selectable 300 ms response time when signal dampening is needed.
• Meeting the NAMUR NE21 recommendations, this device ensures top measurement performance in harsh EMC environments.
• The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
• Excellent signal / noise ratio > 60 dB.
• A green front LED indicates normal operation, status of the input sensor and malfunction.
• Wide ambient temperature range: -13 to 158˚F (-25 to 70˚C).

Mounting, Installation, and Programming

The slim 6.1 mm housing allows high-density mounting on standard DIN rail (up to 163 units per meter), optimizing space in control cabinets and panels. Flexible 24 VDC (±30 %) power via connectors and comprehensive terminal protection against over-voltage, polarity reversal, and short-circuits ensure dependable operation. A front-panel LED clearly indicates normal operation and sensor status. With a rating for wide ambient temperatures -13 to 158˚F (-25 to 70˚C), and approval for safe Zone 2 / Division 2, and marine environments, the PR3101 TC temperature converter is an ideal choice for precision thermocouple signal conditioning in demanding installations.

• Easy configuration via DIP switches.
• Selectable DIP settings for easy configuration of more than 1000 factory calibrated measurement ranges.
• The narrow 6.1 mm housing allows up to 163 units per meter.
• 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.
