Feeder Terminal
Technical Reference Manual, General
For further information, about the external interface units, refer to the Technical
Description of the module concerned. (See "Related documents" on page 10.)
The serial interface RS-485 on the rear panel (connector X3.3) is used for
connecting the feeder terminal to the SPA bus or the LON bus. The SPA/LON bus
is connected via the RER 103 Bus Connection Module fitted to the 9-pin D-type
subminiature connector and screwed to the rear panel.
The connectors X4.1...X7.2 are 18-pin detachable multi-pole connector strips with
screw terminals. The male part of the multi-pole connector strips is fastened to the
printed circuit boards. The female parts, including accessories, are delivered
together with the feeder terminal. The female connector part can be secured with
fixing accessories and screws. One max. 1.5 mm
can be connected to one screw terminal.
The digital inputs and outputs (contacts) of the feeder terminal are connected to the
multi-pole connectors X4.1...X7.2. The auxiliary power supply is connected to the
terminals X4.1:1 (positive) and X4.1:2 (negative). When the RTD/analog module is
used, the inputs and outputs are connected to the terminals X6.1:1...2. The feeder
terminal self-supervision output IRF is linked to the terminals X4.1:3...5.
Protective earth is connected to the screw marked with the earth symbol.
The connectors are designated according to the module slot in the REF 54_ terminal.
