DEC-H85-TDS/TTD – Decoder board for H85/TDS – H85/TTD keypad selectors (2 channels)

The DEC-H85-TDS/TTD decoder board is designed to interface with the H85/TDS and H85/TTD keypad switches, providing a robust, accurate, dual-channel code management system. Thanks to its compatibility with 24V AC/DC power supply and the plastic housing with IP54 protection, the decoder guarantees reliability both indoors and outdoors.

It supports up to 500 user codes, configurable from 3 to 6 digits, and allows the connection of two keypads at the same time. The two pure contact relay outputs operate in deadman mode, keeping the control active until the button is released: a perfect solution for gates, automatic doors, industrial gates and controlled access systems.

The device has a low power consumption and high installation flexibility, with wiring up to 100 meters distance between the keypad and the decoder.
