The address lines are fed in via a transceiver, not shown here, via which the data of a data bus are received and via which, if applicable, reported data are fed into the data bus.
  • the module shown in FIG. 3 below is the base module, while the module shown above as an active module is a power module for switching a motor.
  • the power cables of the 24 V line of the operating current bus, designated 45 and indicated only schematically reach the two connecting terminals 23, which are connected directly to the lines 46 of the output 20.
  • the input 19 is directly connected to the output 20.
  • the inputs 17 and outputs 18 for the data bus located below the inputs and outputs 19, 20 are connected to the circuit board 61 arranged in the space 24, on the plug 64 of which the circuit board of the transceiver, not shown, is attached.
  • the data bus is also connected through the board so that the data bus is not interrupted regardless of the switching status of the remote station.
  • the address lines lead from the circuit board 61 to two parallel input plugs 60 on the two connection surfaces 55 of the module base.
  • the connecting terminals 21 are each connected to the individual wires of the 380V line, which enters the module base 36 via the input 47 and exits again via the output 48.

  • the plug 62 connects the boards 61 to one another.
  • connection terminals 21 are wired to the associated connection terminals 30 with the interposition of the switching elements arranged above and not shown here.
  • This module works as a power module with the corresponding circuit breakers (triac's). The power connections up to the circuit breakers take place via the connection holes 63.
  • the connection terminals 30 act as a power outlet and the cables are connected to the associated consumer through the output 48, e.g. Engine directed.
  • the remaining inputs and outputs of the power module can be covered by blind covers if they are not required.
  • the two outer connection surfaces of the two module bases 36 are covered by end plates 31 in order to form the necessary tight seal towards the outside.
  • each of the modules has all the necessary connectors for each type of function of the module.
  • the connection of the individual data and power lines is possible with simple means and the connection paths are very short. No additional space is required for the connections.
  • the modules are extremely easy to service because the active components can be easily unscrewed and replaced.
  • two adjacent power modules can also be used for switching a motor, so that the cable cross sections within the power modules do not have to be changed, since these cross sections of the power modules add up.
  • Each remote station comprises at least one module, namely the basic module.
