Limit-value switch for temperature, input Pt100/Pt1000 with two-wire-circuit 1 Straightforward application Suitable for severe operating conditions Compact construction Limit value freely adjustable by drum scale Anti-tamper seal for drum scale Meet high EMC-requirements Umgeb. Amb. Temp Temp: : Limit-value switches Volt-free output as change over switch contact Open-circuit or closed-circuit variants available Short circuit monitoring of input signal Broken-wire monitoring of input signal Operating characteristics displayed by integrated LEDs Flame-inhibiting and self-extinguishing body Suitable sensors are available (NORIS sensors TP.1, TP.2, TP.3) Limit-value switches of series 5 Limit value switches of the series 5 are designed to monitor and process electric measured variables. Working principle: When the actual value of the measuring signal supplied reaches the setpoint, the built-in relay will operate. The switching status of the relay contact may, for instance, be monitored or individually processed by a machine controller. General notes on Type RP5.., RPT5.. Description RP5.. and RPT5.. The limit-value switches RP5.. and RPT5.. are designed for the mum value of the sensor signal will be passed downwards, causing temperature monitoring with platinum Pt100 RTD (RP5..) or Pt1000 the relay output to operate and the red LED to light up. To identify RTD (RPT5..) according to EN60751 Class B in two-wire circuit. A sensor failure, the green LED will be ﬂashing to signal a short circuit platinum resistor has a positive temperature coefﬁcient which means that the resistance increases as the temperature rises. Access is provided to a trimming potentiometer to permit a line compensation Volt-free relay contact, closed-circuit or open-circuit version to be applied for Pt100 RTD limit-value switches. Pt1000 RTDs do A volt-free relay contact is provided as a change over switch not require such compensation because, in principle, line resistance contact for outputting and further processing. In addition, there is a can be neglected. For better adaption to the required measuring task choice between closed-circuit and open-circuit devices. three measuring ranges are prepared: 0 ... 150 °C, 0 ... 120 °C, 0 ... In the case of closed-circuit devices, the output relay is pulled 200 °C. Settings of the limit value are made at the short top side of up in the normal state of operation with the supply voltage applied. the switch by means of a drum scale. The scale is graduated in de- It drops off upon the limit-value being exceeded or if the supply volt- grees Celsius to suit the speciﬁc measuring range. Any value on the drum scale can be selected as the limit value. In the open-circuit variant, the output relay pulls up when the limit-value is exceeded with the supply voltage applied. Failure of the Monitoring for short circuit and circuit integrity voltage will not result in any switching function below the limit value. The RP5.. and RPT5.. type series comes equipped for monitoring sensors for short circuits and integrity. In the event of a wire break, the maximum limit value is exceeded, causing the relay output to operate, the red LD lighting up just as when the limit value is exceeded in regular operation. In the case of a short circuit occurri
