Technical Data

General

The unit LUW 1398/3-S02 was developed especially for locomotive applications. Capable of monitoring DC currents of 3 lamps, the unit provides multiple solid state relay outputs for indicating the lamp in which a failure has occurred. The solid state outputs can be used to drive an audible signaling device, a centrally located computer, or signaling LEDs. The unit measures the currents which are supplying the lamps. Each measured current is monitored. If one of the 3 currents exceeds the adjusted limit, the corresponding internal solid state relay is switched on. For each input channel there are two separate solid state output contacts provided. These contacts are isolated from each other and can be used for different tasks.

Function

• Measuring resistance only 40 mOhm
• current value is factory specified
• over- or underflow of the current value is monitored separately for each lamp
• switching contacts are protected by bi-directional suppressor diodes with 33V breakdown voltage
• relay current max. 100 mA

Power Supply

• 16.8 .. 31.2 V DC, no galvanic isolation
