Eltako Bus coupler RS485

Bus couplers for wire connections of the bus and power supply bridges series 14. Cross-wiring bus and power supply with plug bridge. The bus coupler FBA14 can connect various bus components as well as feed power supplies. Bus components on different mounting rails or in other distribution boxes or control cabinets are connected with one FBA14 and a 4-wire shielded bus cable, such as a telephone line. The total length of all connection cables should not exceed 100 m, and a second termination resistor, only 9 mm wide, must be plugged into the last actuator, which is included with the FAM14 or FTS14KS. The position of the bus coupler in a device series of the series 14 is arbitrary.
