Brand Steady-On LEDs, Red Color

PROTECTED LED® is an integrated light module offering special control and protection circuits, which negate the effects of electrostatic discharge, capacitive coupling and electromagnetic radiation. In addition, these protective circuits inhibit LED illumination due to proximity switch or PLC I/O module leakage currents. The protection device prevents spurious LED illumination by absorbing any interference, such as the energy resulting from coil de-energization.
