UKA III Gas Detection Controller

UKA III – GAS DETECTION CONTROLLER

The UKA III Gas Detection Controller is a versatile and reliable solution for monitoring toxic, flammable, and refrigerant gases in industrial and commercial environments. Designed for seamless integration with multiple DEGA gas transmitters (NB III, NS II, NS III), the UKA III offers intuitive operation, real-time LCD display, and customizable alarm thresholds to ensure safety and compliance in critical applications such as HVAC systems, refrigeration plants, and confined spaces. A maximum of 4 (UKA III4) or 8 (UKA III8) transmitter can be connected to the UKA III gas controller. It is also possible to connect a flood sensor and a temperature sensor. The control panel can be equipped with a maximum of five common relays.

RS485 BUS - EASY INSTALLATION

The current concentrations, as well as the status of the individual transmitters, are displayed on the large LCD display of the UKA III. A simple and fast configuration of the complete system takes place via the keyboard and the intuitive menu navigation. The UKA III control panel supplies connected detectors with power. The point detectors are connected sequentially to the control center using the daisy-chain method via RS485-DEGA protocol. This means that only one detector must be connected to the control panel and the other detectors are simply connected to each other one after the other.

This type of connection means a simplification of the installation and thus also a reduction in costs. The UKA III gas controller can be connected not only to the NB III transmitter series, but also to the NS III series (ATEX Zone 1) and NS II series (ATEX Zone 2) transmitters.

The user can thus connect different models and types to a control panel and thus take advantage of the advantages of the various transmitters.
