PR electronics 3111 TC converter - isolated. 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 EMC performance and 50/60 Hz noise suppression.
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.
