The IL Series 12-inch LED railroad grade crossing signal module is a red warning indication for rail crossings. Its published specification lists 8–20 Vdc or 8–16 Vac operation, 9 W power draw and red or white side-light model options. This page covers the IL crossing module, distinct from the EV crossing family and IL transit-indication models.
For agency and integrator selection, check the controller output, housing fit and specified optical indication against the downloadable IL data sheet. The sheet identifies TSL-12RCS-ILR-E1 with red side lights and TSL-12RCS-ILW-E1 with white side lights.
