4.1.3 Communication port TETA BUS
The port is designed for digital transmission based on the Teta Bus protocol and dedicated for devices of the
Teta series. This port also allows you to connect a Control V Valve Controller.
See section 6 for details about the system interconnections.
The transmission line of the port needs a specific polarity. See section 8.4.2 for details.
4.1.4 Relays output
The module has six universal relay outputs. These outputs can adopt one of the two statuses: active or
inactive (the active state means that the voltage has been given to the relay coil). Terminals of relays can
switch over to the following positions:
Figure 4: Relays in active and inactive state
Relays status can be checked by the user interface. Details – see section 5.8. Technical specification of
outputs – see section 17.
The subsequent tables summarize functionalities that can be assigned to relay outputs of the Control Unit
Module Teta MOD Control 1 depending on the specific program of the system operation.
