Bus temperature sensor pure white glossy for connection to the RS485 bus gateway BGW14. For single mounting or mounting into the E-Design55 switching system. 80x80mm, 17mm high. Installation depth 33mm. For installation in 55mm switch boxes. Data transmission and power supply take place over the 4-wire bus with a 12V DC mains adapter. Only 0.1 watt standby loss. For installation in 55mm switch boxes. Data transmission and power supply take place over the 4-wire bus with a 12V DC mains adapter. Up to 16 BTF devices can be connected to the RSA/RSB terminals of the RS485 Bus Gateway BGW14. The permitted total line length is 1,000 m. The second 120Ohm terminal resistor supplied with the BGW14 must also be connected to the RSA/RSB terminals of the remotest BTF device. We recommend stainless-steel countersunk 2.9x25mm, DIN 7982 C, for screw connections. Both with rawl plugs 5x25mm and with 55mm switch boxes. Set of 2 stainless-steel countersunk screws 2,9x25mm and plugs 5x25mm are enclosed. The bus temperature sensor sends a message on the RS485 bus within 20 seconds when there is a change of min. 0.15°C in the actual temperature. Measurement accuracy is approx. 1°C.
