Discrete Input Tower Light

IT40SA, IT50SA, IT60SA Series
- Discrete input tower light
- Energy saving, maintenance free LED lights
- Bright and even illumination
- Number and color of LED modules can be freely combined
- Rugged IP 65* construction is ideal for harsh industrial applications

Depending on the model.
*. IP 65, Vertical mounting only (bottom connectors excluded)
The IT40SA, IT50SA and IT60SA Series are preassembled tower lights of 40-mm, 50-mm and 60-mm diameter LED modules.
Lighting is controllable with PLC. Blinking and buzzing are controllable with PLC (except ITxxSA3).
Direct & Pole mounting Tower Light, Model ITxxSA2 and ITxxSA3 are added to the existing Tower Light Series. These models have 1-5 layers and have small height, thus compact size compared to existing ITxxSA1.

Application Examples

ITxxSA1 Series Component Identification
- Triple-Reflection System
- Our original triple-reflection design prevents the LED lights from wasteful diffusion and ensures effective and even lighting in obliquely downward directions.
- Setting Panel & Status Indicator LED
- DIP switches on the side are used to select blinking frequency (2 Hz or 10 Hz), alert sound (buzz) ON/OFF frequency, loudness level and to specify either the lights should be turned off or maintained in case of communication failure. Power is also provided on the side.
- Five-layer, Five-color LED Modules in Free Combination
- Number of LED module layers can be specified from one to five when ordering. Five colors (red, amber, green, blue and white) can be freely combined for each module.

ITxxSA2, ITxxSA3 Series Component Identification
- Triple-Reflection System
- Our original triple-reflection design prevents the LED lights from wasteful diffusion and ensures effective and even lighting in obliquely downward directions.
- Five-layer, Five-color LED Modules in Free Combination
- Number of LED module layers can be specified from one to five when ordering. Five colors (red, amber, green, blue and white) can be freely combined for each module.
