Programmable threshold switches for rail applications

Programmable threshold switches for rail applications

The LCON Rail Infinity threshold ‘all in one’ switches are aimed at the rail sector and are the first combination units that integrate two potential-free threshold switches DC 110 V / 1.5 A as well as a very precise analogue output in one casing.

This combination benefits manufacturers and operators with space savings in the control cabinet and less wiring, and only one product type needs to be kept on stock in production.

The switches are also suitable for rail companies that do not even need threshold switches but are looking for a converter that is operated e.g. with 110 V and can measure voltages up to 300 V. The switches have a wide range power supply of DC 24V to 110V making them suitable for use in different rail onboard supplies across the globe. 

There are two models: The analogue/analogue threshold switch has measuring input for voltages up to AC/DC 300 V and currents up to AC/DC 10 A (True RMS), and is suitable for monitoring batteries in vehicles with 110 V onboard supplies. The temperature/analogue limit switch is also suitable for monitoring the temperature of axle bearings and has measuring inputs for PT100/PT1000 with 2, 3 or 4-wire, thermal elements, potentiometer and resistors.

The threshold switches can be configured using the free FDT/DTM software. The configuration can be loaded onto the unit via a USB service cable. Both threshold switches have a galvanic 5-way isolation.
