Product description
DEGA UPA III - The third generation compact evaluating controller
is designed as a separate device used for mounting on a
wall or on distributors. It is used to supply up to 32 transmitters via RS485 and up to 8 transmitters via current loop. It
evaluates the gas leak of the transmitters in 4 levels. It is also possible to connect one flooding sensor DEGA ZC II and one
temperature sensor DEGA Tc II. The status of each transmitter is indicated on the LCD display of the controller. The controller
