Limit-value switch, input DC-voltage 1 Straightforward application Suitable for severe operating conditions Compact construction Galvanic isolation of the input and Anti-tamper seal for drum scale Limit value freely adjustable by drum scale output signal to the supply voltage • Limit-value switches Meet high EMC-requirements requirements Volt-free output as change over switch contact or make-contact Open-circuit or closed-circuit variants available Test function to simulate an increased sensor signal without critical machine loading (RG5...-S) • Latching function of output relay (RG5...-S) Short circuit and broken-wire monitoring with live-zero signals Operating characteristics displayed by integrated LEDs Flame-inhibiting and self-extinguishing body 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 RG5..

Failure of the • Devices from 2 ... 10 V/DC with live-zero-monitoring voltage will not result in any switching function below the limit value. • Limit value settings possible over complete input range by means of drum scale Test function for open circuit devices The Typ RG51-S have the integrated special functions testing and Integrity and short-circuit monitoring of input signal latching. The testing function offers while the contacts 2 and 5 are con- The integrated signal monitoring of the live-zero device provides nected, the limit-value signal selected on the drum scale is lowered by monitoring of the sensor signal for broken wire and short circuit.

Limit-value switches with 0 ... 10 V/DC input are not available with broken-wire and short-circuit alarm of the sensor circuit. Latching function for open circuit devices Open circuit devices can optionally be equipped with a latching Volt-free relay contact, closed-circuit or open-circuit version A volt-free relay contact is provided as a change over switch contact for outputting and further processing. In addition, there is a function (see type code). When the limit value is exceeded, the relay keeps activated even if the signal falls below the limit value afterwards. The device has to be reset by disconnecting the supply voltage. choice between closed-circuit and open-circuit devices. In the case of closed-circuit devices, the output relay is pulled up in the normal state of operation with the supply voltage applied. It drops off upon the limit-value being exceeded o
