Installation Din Rail; Lte Modem; Ethernet; Sample Cabling Connection - DEGA UDA III User Manual

Installation DIN rail

Any components with a maximum power loss of 50 W can be mounted on the DIN rail.

LTE modem

The LTE modem is connected to the marked terminal board, or it is already installed from the factory.
Connect the GSM antenna to the SMA connector and take it out of the box as shown.

Ethernet

Connect the Ethernet cable to the processor card and secure it with hooks as shown.

Sample cabling connection

In this chapter, we will show a sample connection of the control panel
1) 2 transmitters are connected in redundant mode - circle topology on LOOP #1 loop - RS485_BUS #1 and RS485_BUS #2
lines. In the event of a wiring failure at any point in this loop, communication with any transmitter will not be lost
2) 3 transmitters are connected in bus mode on the RS485_BUS #3 line. If the cable is interrupted, the transmitters will
stop working after this interruption
3) 1 shut-down button connected to TL terminals
4) The control panel is powered by 24V from the backup UPS and is connected to the control signals of the control panel
5) The sound signal is connected to the sound_sig output
6) Optical signaling (non-ATEX) is connected to the light_sig input
7) Optical signaling DEGA MR-EX II (ATEX - ia safety) is connected via a zener barrier to relay 20 and powered from 24V
OUT output
8) RE1 controls the actuator - at rest, the contacts are open. They close at a defined event (alarm, fault, etc.)
9) RE2 controls the actuator - at rest, the contacts are closed. They open at a defined event (alarm, fault, etc.)
10) Data transfer to the visualization is ensured by RS485_HOST
