Push button gateway for FTS14 systems. Standby loss only 1.3 watts. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 2.5 division units = 45mm wide, 58mm deep. For better heat dissipation, a ventilation clearance of ½ division unit must be maintained on the left side; use the enclosed DS14 spacer for this. Supply voltage 230V. Connection to the Eltako RS485 bus. Cross-wiring of bus and power supply with jumper. Operation in conjunction with FAM14 or FTS14KS. With up to 3 FTS14TG button gateways, the telegrams of up to 90 4-way bus buttons B4T55E or bus button couplers FTS61BTK, FTS61BTKL and FTS61BTK/8 connected via a 2-wire button bus can be fed in with the conventional buttons connected to them. Data transmission and power supply are carried out simultaneously via just 2 wires. This eliminates the need for numerous individual button control lines. An FTS14EM may then not be required. Up to 30 B4T55E, FTS61BTK, FTS61BTKL and FTS61BTK/8 can be connected to an FTS14TG button gateway. The 2-wire bus supplies the connected devices with 29V DC and simultaneously transmits data. Please only use standard bus or telephone lines. The 2-wire bus is galvanically isolated from the Eltako RS485 bus. The permissible total cable length is 200m. The RLC element included with the FTS14TG must also be connected to the BP and BN terminals of the bus button or bus button coupler that is furthest away. With an FTS14FA in the Eltako RS485 bus, the button telegrams from the connected devices are also sent to the Eltako building radio.
