Radio receiver module - Bus coupler for bus system FEM

Radio receiver module - Bus coupler for bus system FEM – Eltako – 30014016 – 4010312313848: Radio receiver module FEM bus system radio bus, other bus systems without, radio bidirectional, surface mounting type, width in modular units 0, other type of attachment, radio receiver antenna module for the RS485 sub-bus. Standby loss only 0.5 watts. SMA socket for the enclosed small antenna. If a larger radio antenna FA250 or FA200 is connected in an optimized position, the reception range can be increased. Housing dimensions LxWxH: 78x40x22mm. Up to three radio receiver modules in their own miniature housing can be installed anywhere in the building in addition to an FAM14 and connected to the main bus with a 4-core shielded sub-bus line (e.g. telephone line) via a gateway FGW14. To do this, connect the RSA/RSB terminals of the FEM to the RSA2/RSB2 terminals of the FGW14. Also connect the +12V/GND terminals of the FEM to the +12V/GND terminals of the FGW14. Several FEMs must be wired with one cable in the form of a chain, as is required for RS485 bus systems. Star-shaped wiring with one line per FEM is not permitted. The jumper must be plugged into a different position for each of the three radio receiver modules. To do this, carefully open the housing at the intended point on the narrow side with a screwdriver. Blade width 6.5mm, max. 1.5mm thick.
