POLTECH's products have high quality - this include everything from each single diode to the whole operating system. Our products are designed to operate during many years. High brightness AlInGaP LEDs are the foundation in our signs. ALC (automatic light control) in all our signs enable automatic continuous adjustment of the light intensity. This means optimal visibility both day and night. Our signs are developed to operate as individual units or as parts in a network. Our communication interface POLNET can handle up till 63 signs. Message update can also be done with for example TCP/IP, Minicall or GSM/SMS.

The signs can be designed completely after your desires.

LD-signs

The LDs are full function signs with 16 characters as standard length, but of course other lengths are possible. The character height is possible from 18 mm. It is easy to write and update messages with IR-keyboard (enclosed) or PC-software. Up till 99 messages can be saved in the sign that holds 7000 characters. Messages saved in the sign can be adjusted to be shown at particular times. It is also possible to insert time or temperature in a message. The text can be shown in different ways, for example static, alternating, flashing or moving. The signs can be adapted for communication with other equipments.
