TTL-485-2

  •    In Stock


Details

The TTL-485-2 is a compact, rugged, industrial-grade, bi-directional RS485 to TTL converter / adapter, which can be used to convert 2-wire RS485 to 5V DC TTL-compatible levels and vice versa. This industrial RS485 to TTL converter / adapter supports multi-drop RS485 networks and can be used to communicate with one loop of up to 128 units of RS485 devices. It operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), and features 600W surge protection and 15kV static protection. This industrial TTL to RS485 converter / adapter is powered from an external 5V DC regulated power supply (included); it supports data direction auto-turnaround, which automatically enables the RS485 transceiver when data is present on the TTL side. Therefore, it requires no software drivers or flow control, making the unit a highly reliable and truly plug-and-play device. The built-in 120-Ohm terminator (for system reliability and easy installation) can be turned ON or OFF through a simple jumper setting, thus making the device an ideal solution for all types of installations.
