LED Railroad Power Off Indicator

Name: LED Railroad Power-Off Indicator | LEOTEK
Brand: LEOTEK

Availability varies by configuration; see the specification sheet.

The LEOTEK LED railroad power-off indicator provides a red or white warning indication for rail-system power-loss monitoring. The published sheet separates its 7–18 Vdc operating supply from its 55–240 Vac detection input; the AC value is a detection range, not the indicator’s supply voltage.

The specification lists TSL-POK-WCF-AB1 at 2.5 W and TSL-POK-RBM-B1 at 2 W, with an optional -WG Wago connector suffix. Check the detection wiring, controller interface and selected color against the project drawing before specifying the unit.
