Taster gateway for FTS14 systems. Standby loss is only 1.3 watts. Connection to the Eltako RS485 bus. Cross-wiring of the bus and power supply with a jumper. Operates in conjunction with FAM14 or FTS14KS. For better heat dissipation, a half ventilation gap must be maintained on the left side; use the included spacer DS14 for this purpose. Supply voltage is 230V. Up to 3 Taster Gateways FTS14TG can feed telegrams from up to 90 four-fold bus switches B4T65 and B4FT65 or bus switch couplers FTS61BTK and FTS61BTKL connected via a 2-wire switch bus with the conventional switches connected to them. Data transmission and power supply occur simultaneously over just 2 wires, eliminating numerous individual switch control lines. An FTS14EM may not be necessary. Up to 30 B4T65, B4FT65, FTS61BTK, and FTS61BTKL units can be connected to one Taster Gateway FTS14TG. The 2-wire bus supplies the connected devices with 29V DC while simultaneously transmitting data. Please use only standard bus or telephone cables. The 2-wire bus is galvanically isolated from the Eltako RS485 bus. The maximum total cable length is 200m. The RLC element included with the FTS14TG must be additionally connected to the terminals BP and BN at the most distant bus switch or bus switch coupler. With an FTS14FA in the Eltako RS485 bus, the switch telegrams of the connected devices are also sent to the Eltako building radio.
