PHOENIX CONTACT PSM-ME-RS232/RS485-P 2744416 INTERFACE CONVERTER T268967

The PSM-ME-RS232/RS485-P (Part Number 2744416) is a high-performance industrial interface converter. It is designed to bridge the gap between a standard PC or controller's RS-232 (point-to-point) serial port and the more robust, bus-capable RS-485 or RS-422 industrial networks. This device is a "gold standard" in industrial automation because of its 3-way electrical isolation (power, RS-232, and RS-485 are all electrically separated), which protects expensive equipment from lightning strikes, ground loops, and electrical noise.
