Wire Saver Tower Light

The IT40S, IT50S and IT60S Series are preassembled tower lights of 40-mm, 50-mm and 60-mm diameter LED modules. They feature direct control by PLC via Ethernet Modbus/TCP (model: ITxxSRE) or CC-Link (model: ITxxSRC).

In combination with M-System’s remote I/O modules, local discrete signals can trigger the light modules connected with single network cables via a remote PLC, saving a great part of parallel wiring from sensor devices to the PLC’s input cards, and from the PLC’s output cards to the lights.

Contact input type (ITxxSA1) without network connection is also available for local control.

Triple-Reflection System

M-System’s 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 and network status indicator LEDs are also provided on the side.


Network Connection

RJ-45 connector for Ethernet or a separable tension-clamp terminal block for CC-Link is provided at the bottom of the tower for easy wiring.

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.

Factory Setting Service with no extra charge

M-System has been continuing “Customer-Oriented” policy for over 40 years since it was founded.

We supply our products to customer’s order when configuration setting is necessary (e.g. Temperature range, Ordering Information Sheet etc ). In addition, configuration setting for all programmable products is free of charge by the customer’s request for once when ordering, except for those requiring special engineering (e.g. multi-function PID controllers). We are trying to increase Ordering Information Sheet library so that the customer can specify his/her spec easily when ordering.

This October, I took a national examination of customs and administrative procedures in order to gain a better understanding of my staff’s work and enhance my support for them. It is the only national license in Japan and less than 10% of people can pass it. It was challenging for me but I did my best. I am now nervous until the date of results (the end of November). It seems much longer to me.

My daughter is 17 years old and goes to school by bicycle every day. Two weeks ago, she had accident on the road. Fortunately, she escaped with a minor injury but needed to put two stitches of her feet. In Osaka, Japan, we have heavy traffic jam especially during the morning and evening rush hours, however, most of the roads don’t have exclusive bikeway, and therefore, many cyclists have to go through the road with automobile or go through sidewalk together with foot passengers. It is very danger for all of car driver, motorbike rider, cyclist and pedestrian. I hope government revise traffic rule and organize a transportation system as soon as possible.

I am very jealous of safety transportation system for cyclists in the Netherlands.
