1 PSM-ME-/-P Interface converter for RS- to RS- -/-wire or RS-. Short Description The PSM-ME-/-P rail-mountable and compact interface converters have been designed especially for industrial use in the switch cabinet or switch box. They convert the RS- interface signals bidirectionally to the RS- -/-wire and RS- standard. The devices are simply snapped onto standard EN mounting rails and supplied with V DC or AC. Their particular feature is the multifunctional application: RS- master interface in RS- bus systems Networking RS- equipment RS- range increase to 000 m as interferencefree and fast point-to-point connection RS- interface adaptation to RS- and RS- systems The following features of the interface converter are particularly outstanding: operating modi can be configured - RS- RS---wire - RS- RS---wire - RS- RS- Can be used universally in all common bus systems with UART/NRZ data format and 0/ bits character length Transmission rate can be set between. kbit/s and. Mbit/s Automatic transmit/receive changeover High-quality -way isolation (VCC // RS- // RS-) Integrated surge voltage protection with transient discharge to the mounting rail Supply voltage of V DC or AC to suit the switch cabinet Minimal current consumption/power dissipation If you have any technical questions, please contact us at: PSM-HOTLINE:+/(0) /-0 FAX:+/(0) /- interface-service@phoenixcontact.com Headquarters: Phoenix Contact GmbH & Co.
