The relay board with 8 outputs is an extension module for the Terxon SX and the Terxon MX. Eight powerful relay switching outputs are thus provided to the alarm system. On the motherboard of the Terxon SX, there are 3 transistor switching outputs (with a max. 0.5 A switching capacity), the Terxon MX comes with 1 transistor and 2 relay switching outputs. These switching outputs can be activated by specific events (alarm, fire, or robbery). The board also has 8 "additional" transistor outputs, with a maximum switching capacity of 0.05 A each. These "additional" transistor outputs are used by the relay module. Instead of 8 x 0.05 A, you get 1 A per relay with this board. This increases your options for defining outputs. The wiring is carried out with NO or NC contacts.
