TTL-485_422-2+PWR-5_US-2 RS422 / RS485 to TTL Converter / TTL Repeater (Industrial)
The TTL-485_422-2 is a compact, rugged, industrial-grade, bi-directional RS485 / RS422 to TTL converter, which can be used to convert 2-wire RS485 or 4-wire RS485 / RS422 to 5VDC TTL-compatible levels and vice versa. It is also ideal for extending the full-duplex unbalanced TTL distance. This industrial RS485 / RS422 to TTL converter supports multi-drop RS485 / RS422 networks and can be used to communicate with one loop of up to 64 units of RS485 / RS422 devices. It operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), and features 600W surge protection and 15kV static protection. The unit is powered from an external 5VDC regulated power supply (included); and 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 unit an ideal solution for all types of installations.
