Transmitter LKM432 without self-locking function
The LKM432 is an analogue overtemperature switch for control systems for mounting on the standard rail and is designed for the Pt100 measuring resistor according to DIN EN 60751. When the switching point is reached, a potential-free changeover contact relay switches. The relay is reset when the hysteresis is undershot. Two LEDs additionally display the operating status and the switching status visually. The lead resistance of the two-wire circuit can be compensated on site with the adjustment controller.
The temperature switch is supplied adjusted to customer specifications. A subsequent change of the switching point within the switching range can be made on site with the adjustment controller.
When entering the switching point, please ensure that it is within the temperature range between 0 and 300°C.
Other sensors and larger switching ranges are possible with our digital temperature switches LKM436 (resistance sensors) and LKM437 (thermocouples).
