4683-TTM-3F

The 4683-TTM-3F from Johnson Controls represents a bus repeater type designed to enhance system communication. This unit establishes a connection via RS-485 to RS-485 communication, allowing integration into networks efficiently. Operating at a supply voltage of 24 VAC, the repeater effectively manages data transmission for N2 and BACnet protocols.

The temperature specifications for this device are well-defined, supporting minimum operating conditions down to -25 °C and reaching up to a maximum of 70 °C. It is also built for storage with a temperature range of -25 to 85 °C, ensuring reliability in diverse conditions. Furthermore, the unit functions well in environments with a relative humidity range between 10% to 95% (non-condensing at temperatures up to 40 °C).

Included in the specifications is a power line fuse rated at 0.5 Amps and 125 volts of 3AG type, enhancing the safety and longevity of use. The repeater accommodates a half-duplex option and supports baud rates from 600 to 76.8K, providing flexibility based on network requirements. The ability to connect with up to 32 RS-485 devices makes it suitable for larger systems, ensuring ample capacity for accommodating various network devices.
