PR3111, DIN rail TC converter - isolated

• * Excellent accuracy, better than 0.05% of span
• * Slimline housing of 6 mm
• * Excellent EMC perforemance and 50/60 Hz noise suppression
• * Selectable < 30 ms / 300 ms response time
• * Pre-calibrated temperature ranges are selectable via DIP-switches

Application

• * The 3111 temperature converter measures standard TC J and K temperature sensors, and provides an isolated analog voltage or current output.
• * High 3 port isolation provides surge suppression and protects the control system from transients and noise.
• * The 3111 can be mounted in the safe area or in Zone 2 / Division 2 areas.
• * Approved for marine applications.

Technical characteristics

• * Flexibly powered by 24 VDC (±30%) via power rail or connectors.
• * < 30 ms fast response time with simultaneous sensor error detection when selected.
• * Selectable 300 ms response time when signal dampening is needed.
• * Selectable internal/external CJC.
• * Excellent conversion accuracy in all available ranges, better than 0.05% of span.
• * Meeting the NAMUR NE21 recommendations, the 3111 provides top measurement performance in harsh EMC environments.
• * The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
• * A visible green LED indicates operational status of the unit and the input sensor.
• * All terminals are protected against overvoltage and polarity error.
• * High galvanic isolation of 2.5 kVAC.
• * Excellent signal/noise ratio of > 60 dB.

Mounting / installation / programming

• * Selectable DIP-settings for easy configuration of more than 1000 factory calibrated measurement ranges.
• * The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
• * Wide ambient temperature range of: -25...+70°C
